What game breaking bugs are in DoW2 exactly? Not saying I doubt it, I just don't know if I've run into any of them yet.
The game crashes on a fairly regular basis in 3v3 games. It happened a lot more frequently when I set my graphical settings on high. So I keep things on medium a lot but I enjoy the 3v3 games enough to live with it.
What I can't stand is the unit imbalances. There is a very clear set of units for each army that get the best results and that is at least 90% of the games you play.
If you want to handicap yourself you can try incorporating other units but it's a shame that as diverse as some of these armies are there is little to no reason to use at least half of the units in most games and even fewer of the specials that each leader gets.
It doesn't really have a lot of depth right now. You'll quickly learn what works and what doesn't and unfortunately that leads to very repetitive games.
And the ranking system has become a little frustrating. The idea behind it sounds like a lot of fun but you don't get to choose what upgrades you want your troops to wear and the army painter seems to have been made for the space marines and the other races get only very basic choices.
The only reason I log in and play a few games now is to try and rank up my profile so I can see the cooler stuff on my orks. But it's hardly satisfying now. You have to score 8000 to rank up from where I am and it keeps getting worse. The winners of a game typically score 1000 or more points each and the losers score approx 200 points which means somone is always getting screwed. I'd be happier if both sides scored similar points.
Close games have a score that is a lot closer 500 vs 700 but that is rare. Most game go one way or the other and don't ever stop.
I could go on but I don't see myself wanting to play this game until they make some major adjustments to the unit balances.
