Recuperate is terrible.

[Absurdity]

I play with a 50ms latency and I get this non freaking stop. Like popping warrior LB and then hitting chaotic cyclone, the game decides i died, but then I see my damage happen...

This unfortunately applies to pretty much everything in the game but it's especially noticeable on healer abilities that, well, heal or shield and on abilities that require quick timing like Purify.

I stopped counting the amount of times that I threw an Aspected Benefic on someone at low hp and they died during the time that it took the game to register my heal, or tried to Purify a stun and died in the time it took for Purify to register.

This goes both ways however, I've had just as many occasions where I interrupted a Cure cast or a Standard-issue Elixir cast and they went through anyway while the target was stunned.

This is a fundamental problem with how this game works, it's just not as noticeable in PvE because fights are scripted and damage is incredibly predictable.
