See the thing is, the mantra of that blog is be patient they will eventually fix the bugs so be patient. A lot of people, myself included would rather not pay the subscription until the game is fixed. I admit I've had fun but there are some frustrations that just negate any of the enjoyment I have had.
Mainly it's because of a severe lack of endgame. I'm currently mid 50's valor wise, done the majority of content with the exceptions of Nightmare mode raids and Hard Mode raids due to lack of Republic numbers and just finding myself sitting in Carrick Station looking for something to do. I especially find myself burnt out of PvP due to the number of bugs, ability lag and general frustrations of playing Republic.
The LFG tool is insufficient at the moment and I'd rather do other things with my time til a lot of things are smoothed out.
In short, if people aren't happy with their experience, they'll cancel.
