you still hit for 3k, and that was at the start of season 7, now you obviously hit for more with a ranged more or less spammable ability. For comparison mage needs to cast a full frostbolt for same damage, the one that gets interrupted in one of 4 ways you got to interrupt casts on very short cd (stun, mind freeze, dg, strangulate) + you have hero class survivability meaning only another hero class can kill you (which havent been introduced yet sadly). So quit your whining, you guys are too spoilt with season 5 experience.
Don't be so ignorant. Death coil is restricted heavily by resource cost, it has less than 10% chance to crit in PvP.
This is WotLK, burst lands kills. You take time to cast your frostbolt but it does more damage, has a far higher crit chance, barely any resource cost, is spammable without any setup (though obviously you have to be in a position to spam it without being interrupted) and don't forget mages have absolutely amazing CC and melee lockdown that no other class even comes close to.
If you cast sheep twice on a target, grats, you just did more lockdown than a DK can using a 10 second,25 second, 1 minute and 2 minute cooldown (i.e blowing every cd). And you can do it again after the 15 second DR timer runs out. If your team is nuking down a healer and you CS a cast followed by a deep freeze (or vice versa) which have a 24 and 30 second cooldown respectively, then grats you've done as much lockdown as a DK does on a healer thats being nuked. Mages have higher arena rep than DK's for a reason, your class is simply better in the current arena environment. There is no two ways about it.
And as a mage don't talk to me about survivability. For cloth yours is amazing. I play a warlock aswell, you guys really dont know how good you have it.
And this is just 3v3. You dominate us in 5v5 aswell.
