Solution to unresponsive Weapon swapping

Swapping should cancel any (or most) animations and instantly swap weapons.

If the rule would be: That some animations arent cancelable and most of them are, then the skill cap would increase drastically. Animation cancel is and will always be a advanced mechanic to further optimize the dmg/cc/outputs. I do think it's important that some abilities are not cancelable, like any closegapers or Path of Destiny (Warhammer) otherwise you just cancel it because you know its gonna miss.

I'm not a programer myself, but I studied Game Design (spec. Character Artist) and have some kind of knowledge what it's like to implement this fix.

I imagine the code to be like:
Attack_X > Animation Attack_X > Input Attack_Y > Cancel Attack_X > Animation Attack_Y

After the Input the ability should be on CD, whether you cancel or not (as usual).

I don't know if this would "the" solution. But for example speaking as tank main: Being able to cancel every attack with Shield Block could lead to an extensive combat experience while still keeping a fairly smooth transition (like Monsterhunter World). PvP will be more skill and reaction time relevant and PvE would be easier and more predictable. Can't think of any disadvantage, but high latency. Everyone has the same ability to get the most out of their weapons.

What do you guys think? Would it be too op? Do you guys want not being able to cancel everything, but just to smooth swapping?
