Honestly, I don't understand why people QQ on these threads. I'm a valor rank 53 Sin, I've 1v1ed every class in the game, and while I havent won every 1v1 due to stupid mistakes, I've never been like "Wow, theres no way I could have beat him"
I've beaten fully champ geared ops, marauders, juggs, healers, you name it. My numbers in huttball damage wise arent all that great, but thats because thats not what I go for. I run in dark charge, with dps spec (deception) and dps gear (with shield gen) I taunt, I protect, and I kill.
I slow ball runners, I knock them off ledges, I kill them.
I'm not saying I'm better than you, I'm just saying you're doing it wrong, and its taken you 59 ranks to realize it.
