I’ve never seriously played lock, but I’m giving the class in general a long look for SL and for being one of the two iconic pet classes, warlock still has some real outdated mechanics around that identity still in place today.
Outside of sloth or just never making it a priority, I’m not sure why locks can’t “tame” (or maybe bind is a more lore-ific word for it) demons out in the world for different roles. Locks should have stable slots, with pets that align with similar Hunter categories of pet. It’d be cool to be able to “bind” a demon to a grimoire in some fashion and that represent that pet being “tamed”. It’s a big ask, but it’d also be a chance to introduce glyphs that convert a demon’s appearance to an undead appearance. In an expansion centered on the afterlife, that would be amazing!
I also think it’s way past time for warlocks to be getting a fire and forget pet heal. In an expansion pushing this unusually punishing 6 second summon cast, I think it’s only reasonable that the class be given a realistic set of tools to manage that pet. The message in that big cast time is clearly to make that pet a higher kill target and to force more pet management into the picture. They brought back the insta-summon button, so that’s a start but channeling a heal that costs health is some holdover classic crap. I really don’t feel more like a warlock channeling a heal. To compound the problem in it’s current design, it costs health in lieu of mana. I really feel that higher risk should impart a higher reward - and that doesn’t have to be in the form of a bigger fatter heal. It could clear snares or debuffs, or do something to increase damage temporarily - something that feels unique and warlocky.
