WHM in Endwalker feels weaker and clunkier compared to Shadowbringers.

Overall, there's no impact in most of the kit, even if some actions are serviceable and the animations pretty cool. Since WHM relies a lot on GCD actions, paying both in time/action as well as mana, the lackluster results all add to the feeling of weakness. Meanwhile, the old issues remain and new troubles have popped up with nothing to really offset it. I'm of the mind that for each cost incurred, the effect should improve in proportion.

In terms of Thin Air, the new single-use buff is a far step away from the power that came with the old free casting duration. I get why it was changed (brute-forcing healing checks etc.) but it did take a chunk out of the mana economy. It doesn't feel multi-purpose as the old effect did, and is now relegated to dealing with Raise or AoE-healing costs rather than being an option for both damage and healing.

Aquaveil has a good effect with a good recast timer, but it almost feels like bloat when placed among the slew of actions that between them no longer seem to have any coherent theme, interaction or direction aside from "big direct heal". I don't want to claim that older iterations of WHM had a clear-cut theme aside from that aforementioned between quotation marks, but each addition exacerbates the situation.

As for the Lilybell, singling out the WHM as the trigger for it makes it feel terribly niche, as if it exists solely for group-targeted Akh Morns. Even if every single savage boss will be hitting us with akh morns or akh afahs, using the bell will leave a bad taste in my mouth.

WHM is in great need of an overhaul from the very core, but we're four expansions deep at this point I don't see SQEX ever putting their money where their mouth is and sorting out this head of design and technical debt.
