Puma is an ok unit, but there is a few good reasons it is not a commonly used vehicle; particularly in team games.Building mech HQ - and therefore Puma - means foregoing the Medic HQ (which is pretty much essential for OKW due to their reliance on Infantry throughout all stages of the game).
People using the Puma to justify stupid ideas like moving shreks to Sturmpios are foolish. I really don't understand why people jump up and down and cry and whinge so hard about volks with shreks. Yes, they are cheap, yes the shrek overperforms at long range, but there are _SO_ many other issues with the game that deserve more discussion. OKW (and USF) both have some pretty major design flaws - both positive and negative. Relic's intention of making the WFA armies unique backfired because they did not take the time required to properly balance then against the vanilla armies. Take note that the posters on .org you CONSTANTLY see complaining about OKW OP units will NEVER mention the flaws with OKW (aka abysmal indirect fire, no early-game counter to garrisoned inf, lack of viable late-game muni sinks/artillery/indirect apart from Assault artillery).
I've said it before and I'll say it again.The easiest (and therefore most likely fix from Relic, because lets face it, Relic obviously don't want/cant commit resources to major faction overhauls) way to balance Shrek'd volks is to give the Volks Shrek a long-range accuaracy and/or Vet bonus nerf - which of course would have to be coupled with a much-needed buff to the raketenwerfer.
It's always the most biased, dim-witted people who create and post in threads like these. coh2.org (especially balance sub-forum) has become a joke. Most people with half a clue don't play coh2 anymore or have given up trying to fight the sheer idiocy of most posters on here.
Stop posting Alex, trying to debate with "people" on this site is like trying to teach trigonometry to the mentally handicapped
