Reason 1: I un-subbed was due to the fact I started on one server, leveled to 50, found friends playing on another server, leveled again, have multiple 50's on different servers, would like to get them all on one server and can't. Yes, I know...paid transfer..."someday", got tired of waiting. How me having all my 50's on a destination server that the makers of the game chose for me will somehow make it more overcrowded..i just don't get. I can only log in one character at a time so I don't follow the bad EA/Bioware math. I figure they know subtraction by this point.
2: Too crowded...I like the game, but not enough to put up with the cluster**** that doing dailies became, even though I'm sure that's calmed down by now...12 servers...really? 16-18 would have been better.
It was and is a fun game set in a great universe, but the leveling experience and story were the highlight and after having done that a few times it got old quick and other games are run much better, plain and simple.
