Ok I am a master powers / master light saber temp. Without any type of enhancements I have a defence of 20/20 ranged and melee and with enhancments i top out at 184 melee. What I want to know is am I wasting my time by getting melee def CA's ,because I heard that if i am wearing bio clothing I am automatically capped and any ca will be null and void. Is this true?!
