[Suggestion] Replace Ring of Fire with....
....Meteor.
Yes, given the fact that TB's hp is just woo weak, Ring of Fire does not work too well because TB needs to be close to enemies.
Other than killing creeps, it is useless against demigod.
Instead I want to see Meteor like one in Diable I/II... smaller damage radius than rain of ice and slightly more casting time (0.5 sec) but do more damage.
