Given that the lack of AoEs, or AoE potency, is almost universal across melee, I'd honestly rather see the leveling experience made difficult enough to again oblige some focus targeting, melee's former niche.

By the time any melee has gotten even a single AoE, Ranged are doing 165+ AoE potency per spammable GCD, with Dancer doing 248 in cycles with a 1000-potency AoE per 30 seconds. Monk can only even perform that AoE once per 3 GCDs for at most 143 potency (or an average of ~48 AoE ppgcd). SAM does 100 flat and cannot maintain it. Rogue does 120 flat.

The thing is, trying to keep each of those skills balanced across that range would require heavy reworks of all the AoEs melee classes get thereafter. Or, it just requires us to go back to when CC, focus targeting, and a decent portion of healer GCDs spent on healing spells were each actually a thing.
