Interesting read.. The only problem is in 3 levels that Wizard(37) will get a 36 second perma root. Sorry but there isn't a class out there they can stand up to a Wizard/Warlock nuking at will for 36 seconds. Scary thing is it's AoE too so if you pet is in the area it's useless. Now as a 30 Warlock I did a little math to see how I would fair again a summoner. I can put out between 1100-1300 points of damage in 6 seconds (1+0.5+2+0.5+2=6) and that is with 1 stun, 1 chance to strife and a DoT ticking.
Flashfreeze,
Bellengere's Sapping Salvo and
Suffocating Breath If the person is under level 34 I also have another 1 second nuke/stun I can use
Freeze.. Warlocks/Wizards just putt out way too much burst damage for most classes to deal with. With the short cast time of the Warlock spells and 36 second perma root I have a feeling Warlocks are going to be king of PvP. But I'm a Warlock so I might just be dreaming.. Plus Player > Class when it comes to PvP.
