Something that’s been on my mind a lot is Spell Lock.
It’s our only interrupt. We are the only pure DPS class whose interrupt requires a specific pet, and worse, it’s a pet that has to be close to melee range to use it.
This is a big problem in a lot of ways. The obvious problem is that if you’re doing any content that requires interrupts (read: any content at all), you have to use the Felhunter. Imp and Succubus are just not viable on any fight that requires interrupts, which is a lot of them. Demonology just can’t interrupt people at all, since they have to use the Felguard at all times.
Worse, the Felhunter has to move close to its target to cast Spell Lock, so if you need to rapidly switch targets and interrupt something on the other side of the room from what you were just attacking, you pretty much can’t ever rely on the felhunter to get there in time to interrupt the bad.
The solution to these problem is simple: make Spell Lock baseline and give the Felhunter something else to use as their active ability. Maybe buff Devour Magic to eat 2 effects instead of one, and usable on allies to dispel harmful effects. I dunno.
Shadowlands is the perfect opportunity to give warlocks a baseline interrupt so we’re no longer placed a huge disadvantage by sluggish pet AI and movement.
