The passive skills are like 2% accuracy boost to a single unit, and they are very limited on how many you can have active at one time, nothing to write home about or be concerned about.
To all the people worried, don't be, this game is amazing.
As a very long time CoH fan, I was worried, but no longer, the game is amazing.
Features like real time fields of view and weather have a massive impact on the game, and open up some very very advanced tactics.
Things feel weighty, no longer will an "out of control" tank just explode at the first thing it hits, it will now smash through anything weak enough to not stop it, and then smash into a building causing massive damage.
Vehicle damage is VERY well detailed now, no longer does it feel like you are just whittling down a health bar.
Please guys, don't worry, wait until you've played it.
This is COH and SOME!! Trust me, it's really, really, reallllly good.
