Yoshi-P: "If you want more engaging content, go play Ultimate"

[Shurrikhan]

The BLM approach is due to healing not always needed. It provides another use for those spells.

I'm not sure the diversity of spells, let alone the fun of healing, would be much improved by moving the majority of buttons worth pressing from oGCDs to GCDs (by outright converting most healing oGCDs to GCDs -- with the value of a Medica or Cure II equivalent rolled into each)... I'd still need to think it over though.

That said, I don't see what the "another use for those spells" would be or entail unless you turn a would-be healing spell into something not so constrained by circumstance (e.g., into damage or damage buffs).

To run the UI/AF metaphor, unless you're essentially using a single skill as a toggle for any and all healing spells into new damage ones (a major, but not undeserved, investment in increased kit size), a "BLM approach" can only make half or more of one's kit unusable at any given moment --in effect just greatly reducing freedom and perceived responsiveness-- just as Cleric Stance did before.
