I'm more concerned with how fast it is for my opponents. I break and do the arm flailing thing and eventually get back to what I was doing. I hit them with a fossilize and 0.2 seconds later, they have broken free, dodged and and running around that rock/tower/tree again.
Its server related and it bugs me like you won't believe. Sometimes I'm able to instantly break free and dodge roll in the span of a second, but other times I get stuck and nothing works. Same with casting heals when I need them, offensive spells to finish off my foe, and casting my ultimate which would have put the fight in my favor.
