ppl are way overexagerrating
as a controller player, I've always been a proponent of this
one button combo would be nice to free up more real estate on the primary hotbar so it would be "easier" to reach oGCDs that currently have to live on HOLD L1 + R2 or HOLD R2 + L1 bars by necessity because of space limitations.

It would still be necessary to weave oGCDs in between each press, no one is asking for one button to keep doing all your abilities... but one button combo would let me place more oGCDs closer together on the face buttons so it could be easier to weave them.
