I love the general concept, a corruption warlock seems like a perfect idea, I just think the abilities you gave the subclass doesn't fit too nicely. A DoT melee is already an overused melee ability, like scorch and sunstrike, so I don't think it fits the bill. You'll need a melee ability which will corrupt the enemy, not exactly deal more damage. I Sorta like the super ability, but I feel like it will be easily avoidable, but the users are going to be at a closer range, but thats just me. I also like the perks on the super, so good job. The grenades don't spark to me. They seem a bit dull to me, something like mist grenade I think should be bound to the nightstalker. Something like my planned Blood grenade "A liquid based grenade (more horizontal range, less vertical range), enemies that touch the liquid on detonation, not area of effect, must stand still for a few seconds, would fit this warlock much better. Also the class perks: 1) Simple, but always essential in these kind of subclasses, great job not forgetting 2) Once again, simple, but perfect, this is a PVE subclass however, so it might become a meta 3) Heres the thing, corrupt them, at all costs, a perk like this is nice, but once again, I'm afraid that it might be overused compared to the others. 4) Add "with abilities" after damaging and it'll be a great choice for anyone who wants to use it in PVP 5) Something like this, seems out of place, it just seems there. I like the concept, but it feels like a titan perk 6) Remember What I said about "corrupt them", well I see you did a great job with this perk. A support needs to be near either the enemy or their teammates, this subclass must corrupt the enemies, then retreat back, so goodjob, this will really reward good players
