the 30% debuff is too much, still. When DPS > HPS dps can mindlessly spam attacks to win.
This is not fair, balanced, or meaningful pvp.
Since bioware in it's infinite pvp ignorance decided to have a bolster system for pvp this is a problem from level 10 to 50.
If hps = dps, then the difference in a 1v1 situation is utility.
In swtor, the difference is just more dps.
In a 2v2 dps/dps vs. dps/healer situation the dps can focus down 1 person and ignore the other.
In a 2v2 dps/dps then they need to use various utility to fight each other.
Mindless dps, is bad for pvp. Fix this Bioware.
