Yeah, I see what you mean. No one can blame them for that. But even when our development team learns about new release-breaker bug, we still have to give a rough ETA for the fix.
In this case with SWTOR Update 3.3, we haven't received any ETA, just a word that it's delayed. I was planning to start playing with new character and buy a stronghold on Yavin 4 today, now I don't even know when I get to play and all my plans for today's evening are ruined.
There is nothing worse than waiting for something good and you don't know when it's going to happen.
