Yeah, the topic has been freshly necro’d, but… probably still worth a little discussion as it is now back to being a bad talent again. With the general inactivity of this board I wouldn’t say a 4 month necro is that much of a crime. But it is good of you to record how Doom has changed since then.
Honestly I kind of like the idea of Doom behaving similar to the Inkpod trinket, it makes the talent a sort of Execute style thing that you apply at the start of the fight and just forget about for the rest of the fight. It’s also not necessarily an OP all-purpose talent in this form as some bosses have transitions that will remove the debuff, some bosses are multiple targets that don’t share health and die fairly quickly, etc, things that limits the efficacy of an Inkpod style Doom and promotes swapping to another talent for said boss.
If there was any possible issue with this style of talent it’d be with a Ghuun style boss, where most of the damage taken by the boss is done by non-player effects, taking greatly reduced damage and being an add fight until X phase. With a talent like this a Warlock might be tempted to tunnel the boss, stacking up the debuff for a huge burst once the boss reaches the burn phase. Not very helpful with adds, but also perhaps exploitable fir something like Ghuun where they briefly take 200% extra damage or something before the burn phase. Stack a few warlocks on him the entire fight, watch his health vanish while under the final laser.
I dunno. Merits discussion imo
