While I highly appreciate their initiative to introduce PvP-combos in PvE, they have taken it way too far for Vipers. 8 skills, including interconnected ones, are used by two buttons. It's been two hours now, and I'm still trying to figure out all the Viper skills up to lv30, wherein the most difficulty is coming from lv30 4 new skills.

Sorry, but I think I need a break.
