Expose should let players ignore taunt. Also should have a "Flanked" skill (red anti-taunt icon)

Mechanics are way over complicated for the game as it stands it would require extensive reworking how the abilities activated. Plus between the two of you you basically just circumvented tanks (which we do not need as they're falling in effectiveness) and then reinstituted the idea under a different name with slightly different abilities. Eg, bodyguard is basically RG. I'm all for thought gents I don't mean to stomp on your ideas but it's a wee bit silly that you just tossed out the old system and then put it back in with different more complicated mechanics. :)
