I would rather press 1234 than spam 1111. At least I'm moving my finger, no matter how slight. And therein lies why people dislike the skill consolidation system. It's neither more difficult nor necessarily interesting, it simply feels better. If we had more combos or different branching combos, maybe it'd work better. Currently, it's simply reducing everything to the healer equivalent of spamming Broil. Sure, you have different animations, but it feels very boring to me. Just like it does on them. They aren't going to add 5+ GCDs to DRG either, thus I'll spend most of 5.x spamming 1 and 2 endlessly. I prefer 1234 and alt 1234. As I said, at least I move my fingers slightly compared to not at all.
Regardless, it's not really a solution anyway because it doesn't help the Casters. Even on the melee/tank side, only Ninja and Paladin are crying for hot bar space.
