Healer & Tank DPS (WoW vs FFXIV)

[zipzo]

You can call it optimizing, but for me it's just a case of doing something useful at any opportunity and why would anyone not want to do that?

I'm not intending to be confrontational but this is a bit dishonestly worded.

Just because a healer is not doing something in a given moment doesn't necessarily and automatically mean that said moment was wasted potential. For example, what if not casting in that moment, allowed them to save the extra MP to land a final heal that saves the tank in the final moments of an encounter?

That moment they don't DPS could lead to a moment that those extra resources actually allow them to do something greater than the net result of having DPSed in said moment. Maybe the "standing around" was the useful action, in that case.

So I think this sort of rhetorical question isn't really a fair way to argue the point you're trying to get across.
