Hey guys just want some feedback on this:
I've been searchin the forums and there isn't much about whether toxic and burn should be deleveled. Because i'm not at 70-90 with my warlock- i just want to hear from you guys if these two skills are useful in pvp, pve, or should i just delevel and stick to decayed and curse breath.
Hahaha...once again a longwinded question

In short, no. Toxin and Blaze become very redundant once you can get Decayed and Curse Breath, as you will find yourself relying on the more useful Bleed and Dull statuses that the latter two can give. Even their AOE counterparts don't have very much use since burn/poison can easily be pilled off with the Universal Pills. You can save yourself lots of SP by not leveling the first two DoTs after 40+.
