For $15 a month, I expect access to online servers to play the game.
For them to KEEP getting my $15 a month, there had better be occasional additions to content and improvement which will keep my interest in the game. Been here for over a year. That's probably about the same amount of time I had invested in DAoC, AO, Shadowbane, and some other MMOGs. Also about as much time I put into BF2 until aimbots and rigged servers got ridiculous.
A lot of time and effort seems to be directed at ToD. I hope for the best, but looking at the populations in the various war arenas, AvA, and SEA.... I'm not betting any money on it. The break up of the MA also does not have me convinced, considering how EW, MW, and the two LW have evolved.
A better, or newer game comes along, I move along. What I consider good games don't come along all that often. Most of the offal that game developers excrete these days, not counting the vapor-ware, isn't worth the CD it's loaded on. Pretty eye candy but limited, or very linear, scripted playability.
Maybe I'll move to SHIV online play in two weeks. Maybe it will be PotBS this summer. Maybe it will be ToD (also in two weeks?).
But, interest is starting to wane for me.
