Worst Units in 40k

This BoLS post was a pretty quick job, but I think they do a decent enough job pointing out some bad units.  I disagree with their exact unit choices though.

• Whirlwind
• Mandrakes
• Necron Flayed Ones
• Blood Angel Scouts
• Gorkanaut
• Morkanaught
• Howling Banshees
• Warpsmith
• Vespids
• Roughriders

The Whirlwind isn't great, but it's only 65 points and brings a Str5 ap4 or Str4 ap5 ignores cover large blast barrage.  It competes with better units, but isn't necessarily bad on it's own.  Now the BA variant is just as bad but costs 90pts and you get fast, which is useless on a whirlwind.  This is 40% premium on a marginal unit. Similarly, Rhinos with Fast at 50pts are terrible.  There's a reason I have never once taken a BA Rhino (razorbacks all the way).

Mandrakes have a cool model and always come up around discussions of least useful units.  No grenades hurts every cc unit but the baleblast seems alright, but you have to earn a pain token first.  Probably not good, but I've played DE so rarely that I can't say I have much experience with their codex.  It's pretty much codex Raider/Ravager/Venom and codex Baron/Beastmaster anyway.  I feel like some of their SC are pretty useless as is the court.

Flayed Ones have reanimation protocols and a 4+ armor so they seem pretty resilient.  If they had some options for a special weapon, I could see this unit being decent enough as infiltrators at 13pts each.  As it is, they are the most useless unit in a very well rounded codex that has aged well.  The offensive output is negligible and could hardly be considered anything more than a slight speed bump.  The definitely belong in the bottom 10.

I will agree with BA scouts though.  More expensive per model and for upgrades and getting Red Thirst instead of Chapter Tactics is a raw deal.  Scout Bikes are bad in general, but the BA ones are only a point cheaper the SM (non-scout) bikes and worse off in general. None of this compares to the floating turd that is the BA Captain. More expensive than the SM variant with no option to take artificer armor, pricier upgrades in general, no FOC swaps, and RT instead of CT.  I suspect they decided not to pick on the BAs because they are a feeble old man at this point and were showing their age more than the last 4 codexes released Orks, IG, Nids, SM.

The Gorkanaught is pretty bad. I kind of like the Deffstorm Mega-Shoota a 3D6 shot S6 ap4 gun.  Even still for 245pts it's offensive output is pretty negligible.  It doesn't have an assault ramp, but I think with only a 6 model capacity you probably are wasting points doing that anyways.  Better to put in burnas and swap 3 for meks to keep the thing rolling along.  It's biggest problem is that it's too damn slow to get anywhere.  Similarly, the Morkanught has the exact same criticisms but it can take a KFF that projects it's 5++, making it and everything around it more resilient. I'd take both over Deff Dreads or Killa Kans though.

Not sure what to say about the Howling Banshees.  I assumed everything in the codex was decent.  A pretty common theme throughout this list so far is CC units that don't have mobility.  Similar to Bloodletters, but slightly worse, Howling Banshees are outclassed by everything else in the codex.

The Warpsmith is another cool model. Since most Chaos vehicles have IWND anyways, there really isn't any reason to pick him over a Lord or Sorceror.  I agree with this choice.

Vespids got better, as did everything else in the codex update last year, but are hardly any good.  GW seems to be a premium on weapons with AP3.  The difference between this unit and many others on the list is that this is actually pretty scary on the table.  Usually Tau have so many threats that you would ignore these guys who have solid mobility and a decent gun.  I would make it a priority to kill them.  They do compete with pathfinders and for points with Riptides and everything in HS.

Finally, the roughriders are just flat out terrible.  A guardsman statline but cavalry and a hunting lance.  The offensive output is pretty low.  At least they have grenades.  Don't forget that awesome Str3 HoW.  They don't even get outflank or scout.  They have no role in the army and will do nothing on the battlefield.

I Agree on Flayed Ones, Warpsmith, Roughriders, and Mandrakes in the bottom. I don't want to pick on the BA codex too much, but their Scout Bike, Whirlwind, Captain, Scouts, and Rhino are bottom tier.  Let's just add one placeholder for "outdated BA units".  To the list, I would add

• Deff Dreads - Slow, weak, in a crowded slot.  No reason to ever take them now, not that there was much reason before.
• GK Brother-Captain - you save 25pts over Grand Master but lose grand strategy, options, and stats.  Overpriced for what he is but still scary.  I've neglected named characters, but Brother Captain Stern may be the worst character in 40k.  He can re-roll one to hit, wound, or saving throw per turn but it grants your opponent a similar reroll on anybody at any point the rest of the game.  It costs you another 50 pts on top of the Brother Captain for this 'privilege'
• Exalted Seeker Chariot of Slaanesh- Chariots are better this edition, but still bad.  Only 2 HP, open topped, AV11/11/10.  Even if they get into combat, they aren't very resilient or offensive.  I'm not sure what role they represent.  It's too bad because the model is balls out spectacular.
• Pyrovore - Still bad after all these years.  A heavy flamer on foot for 40pts.  At least it has 3 wounds.  You can always find a better way to spend the points.
• Ravenwing Darktalon - Doesn't really fill a role.  It doesn't have a gun that can do air to air.  Its weapons are short ranged infantry killers, but overpriced compared to all other fliers.

Any other candidates I missed?
