1ST: Rlz sorry but youre stupid. POM ALTER time is one of the most op thing mages can do atm in pvp. You pomy poly healer alter time insta ring both of dps. Most of the high rated mages do it.
2ND: Its known for a long time and I think that the thread name should be 3 POMS as a mage.
When you use POM its cooldown isnt going down until you use it. But if you use POM -> alter time -> lets say you cast water elemental -> alter time back. Now you still have POM buff but its cooldown is going down. So you wait 1.5 min then you have pom buff but its not on cooldown. So you can use something like frostbolt -> pom -> alter time -> bolt -> alter time -> bolt and that way you got 3 instant frostbolts in a row.
