What I see lacking from most MMORPGs to make the combat mechanics fun and an easy fix for boring mechanics is the ability to undo debuffs like stun, snare, freeze, etc. in a single skill. Most RPGs make what I would call a mistake, simply making these "un-debuff" skills worth long CD (which makes it quite weak), making these undebuff skills only undebuff certain CCs like only stun, and only creating at most one of these skills. Having, lets say, two medium length skills that do other things and do undebuffing makes a much more fluid gameplay. For anyone who played something like Drakensang Online back in the days when PVP was not screwed up before the management team changed and set forth the power creep you should know what I mean.
Personally I like RPGs where you CAN 1v3 (of course the 3 are probably not as skilled as you) if you're good while someone else playing the same class (well there isn't a class in Fractured so lets say using similar skills) can't do the same. Basically, a game where there is a high skill ceiling and for those who actually mastered it (top 0.01%) you can pull off stunning feats like a 1v3 (not because of some stupid item build and steamrolling your opponents like you do in mobas like LOL giving you a matchup advantage etc.).
