What is Carve and Spit for?

[Rover1983]

So your saying that a instant skill that restores your MP and is not on GCD and not a combo breaker useless? Na if anything if anything it's one of DRK's great openers.

I use it as part of my opener, Do the DA+ Aggro Combo, Carve and Spit and it's made it like your not even used MP at all! And if you think about 1 min aint really that long of a CD com paired like 5-8 mins so there's a good 5-8 usages there.

Not saying its useless, just saying it was implemented in an odd way. No ties to any abilities, off GCD(Which is welcome) but it just seems like a "random" ability for the lvl 60 skill.
