The only thing Coh3 has going for it atm is potential. The new game excitement has people overlooking the numerous deficiencies and adopting the belief that everything will just be better because its a new game, because relic have been working with the community, because Devm is on the development team, etc etc. The other thing is people are also adopting the attitude that Relic will just fix the issues and the game will be great in no time.
Personally I hope this to be true, and the latest announcement about bug affecting the graphics gives some hope. But I think its false hope. The graphics atm just look crap, especially the desert maps. How anyone can play the game or watch the many streams and honesty say the units visibility is equal or better than the previous two games is simply taking the piss.
As I said previously I hope this is just the beta and that the game on release looks great but I think they are overlooking playability in favour of realistic skins and the weathering of units...
So far, now that graphics were addressed, the only "concerns" people rise comes from preference, not inherit game flaw(pace and game length).
I haven't seen anyone complain about balance as nothing is crushingly imbalanced as it was in coh2 at, well, pretty much any stage of its life.
Now, if graphics look bad for you, it might be your GPU not being able to pull it off anymore as to me, graphics were pretty much on coh2 level, details and shaders will be adjusted, this much we know.
