I played less frequently the past few weeks, because of lag and loss of connection. [and I am a TS to boot]. I don't know if Kyp and crew can solve the lag/logged out problem, but until then, it is hard to keep the population like it was a few months ago.
I know I am in the minority as I play solo and Multiboxed because of my frequent AFK obligations. But recently, I have had toons losing connection on its own, (form of 6 toons, and out of the blue, one of them is no longer responsive).
I think the utmost importance currently is to address the stability of the game.
WIth that said, I try to log in every week especially after Tuesday patch to see if the problems have been fixed.
