OP's suggestion was probably one of the dumbest I've ever heard.
To give it a comparison:
- Tracer Missile with a 20s cd
- Remove Stealth from Operatives
- Remove Force Lightning and DoTs from Inqs
- Remove Rage-generating abilities from Warriors
"but oh wait, you say, that would totally break the calss mechanics!"
BINGO!
Which is exactly what OP suggest, which makes it incredible freaking dumb.
