How is finesse diffrent from Radiance?

[Vhalantru]

I can't exactly answer this but I can give you an idea I guess. In beta when I was lvl 65 hunter I was not able to kill a lvl 71 dunlanding mob. Using hunters art which I think added at the time 500ish (might have been 700ish) was enough for me to be able to kill one of those mobs. That was not what I would consider a clean kill mind you. I squeaked out a win and that was just standing toe to toe blazing away.

Well that mob is 6 levels above you and should be near impossible to hit anyway. Are not even raidmobs under the old system only 3 levels higher than the current level cap?
