Why isn't RDM's Riposte combo tied to one button?

[Eisenhower]

My issue with this, is that if you consolidate a combo, it’s no longer a combo, it’s just one skill you spam.
You may as well remove the other two skills and give it a trait that increases it’s damage with successive hits up to three times.

Isn't this exactly what the True Thrust (290 > 350 > 530, no other effects) and Aeolian Edge combos are right now? The former even more so than the latter, as Aeolian Edge at least has a positional requirement. Just like how it's expected of NIN players to remember how the mudras form ninjutsu, or how players in general are expected to remember how a boss fight plays out, it's not unreasonable to expect a player to keep track of which part of a consolidated combo requires additional movement/position/etc.

It's true that a combo split between three buttons require a fraction more player involvement than a consolidated one, and will invoke more engagement. But it's misguided both in critique and in design to consider consolidated combos in a vacuum. The space opened on hotbars and in attention should be used in other ways - new ways - to engage the player.
