The item comparison feature is crap! been trying it on the ptr. for example if u compare a cloak with agility and crit, and say one cloak got more agi but less crit. Rating buster would have calculated the %crit gained or lost, but the ingame just compare raw number , agi vs agi and crit vs crit. aslo it wont compare gear with attackpower and str correct. just show u (for example u lose 120attackpower but gain 60str.) ratingbuster know if u have talented for extra str and calculate the total ap gain.
the list can go on and on forever:P there is no need to compare raw stats, its as useless as the wowhead compare feture:P
they must change it to compare:
total ap
total melee crit/spellcrit (also from int)%
total SP
total hit%
mana
hp
etc...
dont think for a secon that u can actually use the ingame "ratingbuster"
(and english isnt my native language so u dont have to comment spelling or grammar pls)
