Even with DPS meter you can still watch TV and be top 5 DPSer.
Get a razer naga, g15 keyboard, belkin n52te, and make some scripts and macros. Go watch TV and just use one hand to point your character to the mob you want dead.
SWTOR just made it so people who don't want to spend $200+ and write macros can still watch TV and dps without people being mad that them for not doing good dps.
Since there is no auto attack and such in SWTOR I have such a huge advantage with all the hardwares listed above. When I play I don't even need to spam any buttons. I just toggle it ON or OFF. I just need to target a mob that I want to kill.
