I would prefer if they also keep the current system if they add name based games, cuz I don't wanna see tons of income wars, dota etc flooding my game list. So you could pick popularity when you want too, or pick search for names when you want to look for good games which is far down the popularity ladder.
Also the variety system which prevents the most popular maps from flooding the name list as well.
Also an online bnet 2.0 forum where you can create posts on other users accounts and give feedback on their maps they play would be great. The current upload system kinda makes it much harder to get feedback on maps as users no longer goes on epicwar or other map sites to look for maps since it's kinda all on bnet now.
