I just play the game and realize there are two thing will be help to play the game just little better.
First, it already mentioned before in this community (my topic). But, still not treated so... just write about my opinion in here again... The thing is custom slot which already have in 'Company of heroes 2'. Actually, before the 'Dawn of war 3' series. There wasn't need to add this custom slot. But now there is various doctrines with elites. Nowadays player only one setting for each race. It's not quiet strong needed than new race update. However it will be easier to setting or choose own doctrine with elites before the game started in multiplayer during 60 seconds. Umm... just for 'Quality of life'.
Second, 'Dawn of war 3' has the biggest battlefield with large scale battle. 'Dawn of war 1' is bigger than 'Dawn of war 2' but both of them didn't need to 'Battle field map' which already in 'Company of heroes' series. 'Dawn of war 3' seems like biggest battlefield with own large scale can call the war. But there is no 'Battle field map' like other series. This is not strongly recommended, just for 'Quality of life' or easy to check where is and what happen in the battlefield. 'Company of heroes' has this system because there are large area which need to see all over the warzone. Seems like 'Dawn of war 3' has similar scale of battle with warzone and that's why I mentioned it in here.
Yeah, These are not important than new race or other system update. But just found and mentioned about them for better.
