What is this level 20+ killer combo?

[Ripper McGee]

Please note, I had full health (699) and she took me from full health to knocking me all the way across the room, stunning me and dead from a Vermin Swarm DoT within seconds. Wickedly cool (for the pitcher, not the catcher), but over powered?

Big ups to Neoxdeath (who was kicking my butt) and Vlad Ducantes (my teammate). It was a fun match and Neoxdeath did a superb job of defending the keep against Vlad and I (it was only her versus us at the end). She kept taking us both out pretty easily even though my stats are comparable to hers and I'm sure Vlad's are, too. That points to how overpowered some skills and/or combos are in PvP (and this is post Vermin Swarm nerf).

FYI ,I've been knocked back a lot farther than that, but the corner stopped my progress. It's crazy getting knocked back across what seems like 1/2 the map!
