In any normal content healers do not have to do a single bit of dps and duties are still patheticly easy to complete. Healer checks can often be done with just 1 ability, and otherwise a combination of 3 buttons if they have to be done faster. So any addition into the dps wont hurt this skill floor part at all, as especialy for less good players the focus has to be on keeping the team healthy anyway.
But i hope they will use the condensing of abilities (as they already do for some msq battles), would be used on a healer. While 111 spam might be dull, using it as a base is still welcome. You then can chain in additional abilities that for example is usable every 3rd 1 cast. By condensing you can make quite a combo system with some flexibility, but not having it take up many buttons. With 3 buttons it can be made quite extensive (1AB being the base buttons on the hotbar): 1 being a 123 combo on its own. 2 grants 'A', 3 grants 'B'. Using A converts B into C, or if B was already used, D. And suddenly those 3 buttons already involve 7 dps attacks and 2 branching possibilities (12AD3B,123ABC,123BAD). While at the same time making it barely more difficult (the ABCD buttons only need to grant a little bit more potency and missing one barely hurts, making the GCD part still more relevant)
EDIT: and note, DT doesnt have to instantly make all 3 branching paths either. This can be seperated through several expansions. And provide additional effects towards its chaining.
