i fully agree with Tex here.
but first i want to anwser to some other things written in this thread.
saltychipmunk wrote:Lets examine the other races, chaos get plagues which is mobile , has a snare and is very durable. it is an ideal unit not only for its av rolls but for its tanking roll. In a sense it does its av job and then does other things making it a very flexible investment.
you can easily deter vehicles with just that one unit.
what i want to say about this is, the plaque marines are really expensive and like tex sayed, they were hard nerfed in their durability (1. the reg is much less, 2nd they dont heal themselfes anymore on a death explosion - especially the second fact makes them much much less tanky as u assume. also they are no Heavy Infantery)
Overall chaos got a huge nerf in AV options - it has been sayed yet by tex.
the tzeentch dread is still very good, true, but its the only dread upgrade which makes the dread almost useless vs. infantery.
saltychipmunk wrote:the same can be said for tacs with a rocket , tank bustas and even venom broods. they are all mobile which alone wont get you far, but they have a secondary attribute , spike damage, all of them can fire a volly and run away or at a vehicle.
Tank bustas and Venom Broods do NO infantery damage. both of them are no upgrades but single units which u need to buy seperately.
although Venoms have a second benefit its still not like a Brightlance, Warp Spiders or Wraithguard, which u buy all for other purposes and get the AV
additional to the other good things thees units do- last but not least. you got the Fire Dragons who do massive damage also to other units - they are really powerfull !!!!11
Space Marines is unique to the - i just upgrade my stuff and get what i want immediately.
this is on purpose. and its very expensive to do so.
also SM has really not much AV overall
- Lascan (similar to the Brightlance)
- Rocketlauncher - cost 40 power, does not that much damage, is on a squads which actually needs to do damage to infantery.
Most of the SM sqads are not dedicated damage dealers. Tacs are really nessecary for damage. so its usually a huge blow for damage, when they get a RL (even if they still do dmg) - Sternguard really helpes here, but they loose all their exp gotten in T1
- many reaces can have dreads..
+ T3 stuff (almost every T3 unit in the game is sort of AV)
- the libby lost his Heavy melee
- Plasmadevs barely hit vehicles
- Heroes are excludet (as it is at the eldar side)
its discussable thou.
why eldar heroes still have their AV wheapons but the Chaos Lord lost it. or the Autarch still has his Fusion gun, while the bloodletters lost heavy_melee but this starts to be moaning

ok so give something constructive:
- what about highering the upgrade Time of the Shurican > Brightlance Upgrade?
imho best would be the same time a Bloodcrusher needs to build, so this is not broken anymore and is just about who got the faster t2.
when the shuri is immobilized while the Upgrade like tzeentch havocs or Sternguards its also a solution for Tex´s described problem, sunndenly bein attacked from a bright lance.
