For the love of Pete, add proper action queueing. Seriously, UBISOFT took the worst part of Shadow of Mordor i.e. the controls and made a PvP game out of it. Many of us have the skills to hit what we need to hit, but these inconsistent timings maddening.
If I initiate a stab on someone repeatedly I should be able to hit them 3 times if I hit the stab button 3 times without the game canceling my other two stabs. Same thing goes for the stupid jump and stab with the Peace Keeper.
So far 19 org mates have canceled their pre-orders already because this is so atrocious.
I also think action queuing would be massively beneficial to the fluidity of this game - the combos especially. I often don't perform moves because the previous one hasn't finished yet, and when the animation finishes, the game simply has no idea that I pressed the button for the follow-up ability. It's massively infuriating.
That said, you could argue that this is deliberate and it's a skill you develop.
