im kind of new to swtor pvp, but not mmo pvp. Ive been pvping in mmo's since daoc, and have played damn near all of them to one extent or the other.
swtor pvp is interesting atm because it is new (to me). but right off the bat i could tell the cc was insane. a simple fix (taken from WAR) would be 5-15 sec of cc immunity after you are cc'd. this means you have to choose when to use your cc's a bit more instead of just mindlessly spamming them.
honestly i just started pvp'ing yesterday (got my scoundrel to 36 and got shoot first) and after 2 hours it started to hit me that the cc is really crazy in this game. and after 3-4 hours i could tell if we were going to win just by which classes i had on my team.
not to mention healing on my scoundrel is perhaps the worst implementation of pvp healing i have seen. just absurd really how stupid that is. i rolled a scoundrel primarily because i like healing in pvp. on my chloro mage in rift, or runepriest or archmage in WAR, or druid in WoW pvp healing was a blast. on my scoundrel it was a snoozefest. luckily scrapper spec was fun.
