My very first online game I was playing Rook. I went to cap a flag right after the game started (there haven't even been any creep waves) and I run into Oak.
He proceeeds to beat the crap out of me so I try to use a health pot and BAM "stunned"...
I was still really new to the game so after I take my butt whipping I log into single player and play Oak to learn his abilities...no stun..
So how the hell did he stun me at lvl 2 (maybe 3, but highly doubt it...to early in the game.)
