People can say it's not DRK/AST but it's always the DRK/AST combos that melt entire teams. I've played plenty of FL where I could survive a harrowing encounter against multiple players with well-timed guard, heals, CC, etc. but by the time my guard even takes effect after getting pulled in by a DRK I go from 100% to <30% (or even just outright dead), and I'm pretty quick.

If it wasn't so broken, people wouldn't do it so much and other players wouldn't be complaining about them exclusively.
