Your accuracy reduces by 2% per level relative to your opponent's level. If your lvl 19 is fighting lvl 25s its chance to hit is actually a baseline 88% but if your lvl 19 fights a lvl 23, it'll shoot up to 92%. If your lvl 19 fights lvl 19s, there is no longer a base miss % as so that 100% hit ability should always hit (barring things like Sandstorm, Blind, etc). Here's a link to the post about accuracy stuff, which was rebalanced in 5.3 - ( http://us.battle.net/wow/en/blog/942556 ... 3-4_4_2013
