No not really. The problem is how vague the definition of a dps rotation is.
Is it simply 1-2-3? That solves little and I suspect few people will support it irrespective of if they want more or less healer DPS engagement.
Or when you say 'DPS rotation on par with a DPS job', does that mean all the extra goodies that comes with said core rotation? That would be a much bigger change, but as I mentioned in my response, simply dunking a full DPS kit on a healer flat out isn't realistic and anyone with any sense is going to see that. It would just be far too many hotkeys to be manageable and if it doesn't integrate with our existing kit, it's just going to be a disjointed mess.
However, a tightly integrated DPS rotation kit that empowers and drives our healing throughput at the same time? Hell yeah sign me up for that. I've said it before and I'll say it again. Warhammer Online's Warrior Priest class was perhaps the finest MMO healer ever penned and it absolutely burns me that SE haven't had the initiative to copy that concept and adapt it to FFXIV. It would solve the lack of healer engagement in casual content.
