using trinks,ptions without gcd between it (and sometimes use them w/o cooldown)
i hope this is not a repost (search didn't want to work for me)
first of all on some servers this may be fixed.
anyway here comes the exploit.
if you make a macro with the trinkets/potions in it you will have like 99% chance to let them proc w/o gcd or cd between them (usefull for pvp trinkets and on some servers usefull for potions) only thing you need to do is spam the button to be more sure it will work
/cast Vicious Gladiator's Badge of Victory
/cast Fury of Angerforge
i'm sorry if this won't work on your server
