the only problem i have with wc3 is the number of imbalanced maps. like on footies vs grunts, which used to be a fun map, now has little tiny bunny heroes that are extremely imbalanced. versions before that had an imbalanced marine. Hero Line Wars is corrupt completely, some heroes extremely rape everything and others can hardly survive the creeps attacking them.
another thing i hate to see in the wc3 community is EVERYONE vs 1 person. these maps are dying down but they are still there. in most cases, people never want to be the 1 enemy. there are stupid maps where its 11 people vs 1 "ultra" guy, sure sometimes it may be fair, but no one wants to play a map where they are isolated from everyone else while everyone else is having fun building up bases or what not. like helms deep, people are willing to play as the orc but people always want to be the humans, since they have to hardly do anything except for sit back and sometimes move the hero. one thing ive also found retarded in these type maps is that the orc hero always gets killed and never has a chance to level up, where the human heroes sit back with the archers and get tons of free exp as wave after wave of orcs are sent at them, then you have a lvl 20 hero that cant be stopped.
well, thats my rant on wc3 and some of the maps out.
