When it comes to PvP, your best possible attitude would be one of skepticism and indifference. If you show signs that you care too much about balance, bioware will find a way to disappoint you. Look at the last patch, everybody already knew that after the release of 1.7, thursday, friday and saturday should be days of expecting maintenance. And we were right.
Although there is still a chance for expansion patch notes to put a big smile on my face if they give sniper passive stealth detection
They can give melee ability to reflect my ambushes back at me, but if will be able to pull the annoying bastards out of stealth, i'll call it a day.
