Abilities that grant you additional avoidance aren't contested anyways so not sure what you're looking for. Parry block and dodge all have contested (skill comparisons) and uncontested versions. For contested defenses the cap is 70%. So no, it's not possible to have 100% contested avoidance. This is spelled out in the FAQ so not sure why we're addressing it again. You can get pretty darn close to 100% avoid, but there's no heroic zone hard enough to need it. 1000 blows come in, 700 get parried. 300 blows get by parry, 210 get blocked. 90 blows get by block, 63 get dodged. 37 blows hit, so your contested avoid prevented 96.3%, but wait! There's more! You also hbe another bruiser just as defensive as you avoiding 96.3% of 62% of the 37 blows that got through, or another 22 of them. Now only 15 got to you and you have a defensive spec'd dirge parrying for you too. Add in some uncontested avoid from shield ally and neck adorns and let's throw a wrist from SOH on everybody too just for good measure and you could probably get yourself down to less than 1 in 1000 hitting you. I know last night tanking in raids our wizard kept complaining that iceshield would have the 30s duration expire with 0-1 charges getting used.
