question about hurricane/armageddon
so ive decided to make a pvp fire druid, and i noticed that both hurricane and armageddon can last close to a minute. does this mean that you can stack dmg by recasting (ie cast armageddon, wait for delay, cast again, wait, cast, etc.) over and over? also, for pvm, with pretty gg gear how fast do things die (say mephisto) in a full game? AND what merc should i get?
