And to clarify since certain individuals will try to run away with a false narrative:

A 1-2-3 combo by itself isn't the solution here. It's just bloat and doesn't break up the current tedium. Trying to push a narrative that this is the only solution on the table is flat out disingenuous.

Increasing incoming damage to the point where it actually taxes our existing kits isn't viable in mainstream content. Some time back I debunked some claims about this demonstrating just how much healing a WHM can dish out with Medica II and Lilies alone. Spoiler, it's a LOT, you'd need to have old school Savage HPS checks in dungeons and 24 mans. The ultimate irony is that I'd absolutely love for that to happen. I can promise you without a doubt that you wouldn't though. Think for a moment why so many of the healers here that are written off as 'dps mains' view Godka as one of the best Savage turns this game as ever had. Spoiler, it wasn't because it was a DPS centric fight for us.

It's going to take so much more than the above to freshen up the current state of endgame healing IMO:

We need faster paced bosses that don't routinely sit there for upwards of 30 seconds channeling casts and doing literally zero damage. Here's looking at you Rubicante.

We need more damage being thrown at the tank at all times coupled with the return of both auto attack crits and non telegraphed mini tank busters so that we have to pay attention to the tanks HP bars all the time, not just at key specific moments.

The recipe for dungeons needs a radical fresh pair of eyes. Give us more mid fight adds, give us funky agro, give us mobs that need to be CC'd, give us stuff to actually cleanse. We've had most of these things at various stages of the game's life in the past. Why have they all been forgotten now?

Healer synergy with DPS needs a ground up rethink, why are our buffing options so bland and limited now? Loads of healers don't want to sit there being a Poundland DPS job all day, why do we have 4 jobs and not a single one of them can spend their GCDs buffing the group? Oh right now I remember why...

Sure, leveling roulette can be fun, but that doesn't change what a dumpster fire the casual endgame has turned into. It needs to be addressed to help ease player retention.
