yah im interested in that too lol...
i will say this.. IF you are thinking of fire druid (because I am)
Grizzly Bear + Volcano = stun lock
those swirlies the grizzly bear puts over the head of a enemy go great with volcano.. they get trapped in your volcano basically.. and if armageddon his too.. then it stuns them as well..
however.. I think that for the sake of arguement you cant count on armageddon to hit your enemy in a pvp world... lets just assume its there and if it hits then its an added bonus.. (hurricane doesnt do any dmg either really so i assume they are both negligable as actual killing spells.. )
volcano is the critical peice here i think.
but yah i would like to know about ravens and armageddon interrupting attacks too... good point.
