Combustion Bug

Combustion abusing - As you know, when you use combustion you gain 10% crit with fire spells and adds up until you sucessfully landed 3 crits. However, if you take this talent and stack it up (Usually to 50-70% crit) and then you respec! You will still have the combustion buff on you, even tho you don't have a talent point in it. And the abusive part is that it does not dissepear when you crit. So you will have 60% increased fire crit chance untill you die. Meaning, as a geared mage you will have around 85% crit constantly with your fire spells.
