Sorry but with 2.0 knocking at our doors, all bets are off. I am quite sure that in 2,0 with all these class changes snipers will be completely unable to kill good operative players of any spec. Marauders suddenly got their first 30m ranged attack. Forget everything you knew about SWTOR prior to 2.0. Class match-ups, counter-classes, everything.
You have to start fresh.
Perhaps the most epic "My class is OP and I'm deflecting" post I have ever read on these forums.
