Since there are many complaints spread across multiple threads and a lot of people showing a lack of respect for others, I will try to combine all of them into one comprehensive post for further debate. So, we are all aware of the hate train and as someone who is not easy to get upset over small things, I will give my opnion on the current criticism directed at the game.
The ones I find not justified will be listed first, as I will need to build up the ones I find relevant on these:
Animation is too cartoonish. I don't see this is THAT much of an issue. It does not have the same feeling as other Dawn of War games with models too clean and projectiles too flashy, but it looks alright.
3 factions are too few. I was disappointed myself learning there would be only 3 factions, but after seeing they had 9 Elite units each, I think it is alright. I know for fact they are fleshing out the factions, and that is good. Company of Heroes 2 was released with 2 factions, and because you cannot have mirror match, EVERY single game for one whole year was Ostheer vs Soviet. And people, including myself, still enjoy it greatly. Having said that, how having 3 factions in Dawn of War 3 is a bad thing will be explored later.
It's not lore-friendly. The ONLY thing considered canon is GW published materials (Codex, Supplements, White Dwarfs, etc.). Anything from Forgeworld or Black Library should be taken with a grain of salt. Don't get too upset that your interpretation is not what Relic is going for. Although I wish from the bottom of my soul that Gav Thorpe and C.S Goto atrocities towards the Eldar are non-cannon by all means.
Lack of cover and sync kills. I did not like this at first, but after seeing a few games I can assure you that the implementation of either of these would be impossible. The battlefield is too large with so many models invovled. Also, it is unrealistic that someone would be wholly invulnerable while performing a coup-de-grace.
