As you know avoidance is something we pride ourselves on.

And also at 102.4% avoidance we become UNHITTABLE yes thats right those big nasty monsters wont even be able to touch us !

But its not too practical but heres how to tell how much avoidance you really have pop this into yer chat box and hit enter and it tells you

/run ChatFrame1:AddMessage(format("Unhittable at 102.4%% - you have %.2f%%", GetDodgeChance() + GetBlockChance() + GetParryChance() + 5 + 1/(0.0625 + 0.956/(GetCombatRating(CR_DEFENSE_SKILL)/4.91850*0.04))))

There ye go. get back to me on yer avoidance

Mines is 79.62% whats yours
