LOL at these "I just got facerolled in PvP and am mad and came to the forums to demand swift action to make me better at my class through downgrades to my better competition and upgrades to my own class that I'm still learning how to play" posts.
Sentinels and Marauders drink your tears. They taste so, so good.
Even odds that you complain about pyro spec powertechs.
I tend to groan IRL when I see sents/marauders in group finder, because some of the most obnoxious ignorant people that rush ahead of the tank and generally make ADHD asses of themselves seem to favor the class.
