Coh2 had great stuffs like cold weather ( you had to build fire pits, and take care of ur units during a storm, i dont know why they removed it
), the mud system was also good but when they introduced
usfukfokw and FRP it became very difficult for
sovietsostheer. The commanders, bullitins, skins are also unique. Stuff like jumping over fence etc.
COH2 bad things, for me
sovietsostheer were in good balance, but the rest of the factions seemed like they where made in a rush maybe 1 or 2 weeks. They had nothing unique (maybe OKW veterancy, and USF crew jumping out of tanks). Some commanders are useless. OKW and USF without classic support weapons are forced to blob imo. Maps are just meh, like someone said 1 building captured can decide the all match for example City 17 .
COH1 well i didnt play it so much as coh2 (maybe 20 h) so i cant tell the good stuffs or bad ones.
