I think thew biggest issue with the Holy 2 set is the total rng, as well as not much value in M+. would be nice to have something that impacts M+ equally well.
Compare it to others with flat +% increases in commonly used spells for all content and it seems like they really don’t care to put any thought into the set other than “err…I think holy priests use PoM…so…”
It’s somewhat better rotationally than keeping up the buff, but the numbers on it make no sense. A flash heal for every 2 heals would make a lot more sense, but as-is, it’s really kinda bad - because flash heal just isn’t a very good spell when it comes to HPS or ESPECIALLY when it comes to mana value, and you have to consider you could have just cast heal back to back instead.
Also after playing with it a while, I’ve come to the conclusion that lightweaver ALSO sucks rotationally anyway. I’d rather they just scrap the design entirely, and make a talent that makes heal faster in general. It’d be nice to just remove flash heal from the bar TBH.
The two other healers that have the quick expensive heal + slow larger heal setup (Pally, Shaman) have something else to at least sometimes make you consider the slower heal, and neither of them cast the slow heal that much either. For Shaman, really the only time you’re doing it is primordial wave cleave. Even Tidal Waves (which functions a lot like lightweaver but only 2 talents into the tree) isn’t enough to make them cast it. Paladin’s got a way to make Holy light generate more holy power and make it cleave 2 extra targets (and it is more efficient for tyr’s deliverance uptime). But they’re not casting it either.
The game just doesn’t move slow enough to make those heals feel anything but clunky anymore without other effects. If I’m gonna spend 2.5s casting something, it had better feel good, rather than feel like a slightly better than filler healing spell. And Lightweaver just doesn’t cut it because it’s not even really an HPS gain, as much as it makes heal not feel actively bad to cast.
Lightweaver is worse than Flash Concentration because you can only build up 2 charges at a time which limited your ability to respond to group damage. The constant rotation of Flash Heal + Heal got a bit brain tangling as well because I would often find myself just chain casting Flash Heal or I would be slow casting a Heal.
Divine Image just craps on Lightweaver because even with 1 image out your Flash Heal does more overall healing than LW Heal over 9s. With 2+ images out your Flash Heals are healing basically with the power of Resonant Words. Overall you need to spend less casts to top people off because DI also buffs your AOE heals quite a bit.
Lightweaver is effectively obsolete at this point as a remnant of an old expansion playstyle.
