Wait so instead of actually letting us know of a schedule your letting people just hammer the launcher with logins all day to see whether they actually got in? How is that any different apart from letting us actually know a schedule, at least just a time. Doesn't matter if it's not specific at least it would give us some clarity.
Hell my guild mate is in with only around 90 people on Tython, I would hardly say your servers are being hammered compared to weekend beta.
