Ok first, I should point out that making a dedicated healer (or even a part time healer) is also hog tying your character to "a small number of skills dedicated to not dying".
If you are imaging combat to be the same as in DA2, just without healing, then that would indeed suck, which is why that is NOT what is happening in DA:I. Combat has been rebuilt from the ground up to be balanced around not having access to healing.
I'm assuming you haven't seen it, so this post explains it very well (I'm really going to have to add this to my sig, lol
)

You will note that the devs 7 year old son played through on Casual for 2 hours with no problem. If that was your plan anyway you really have nothing to worry about.
I really don't get this though. Mages can rain fire from the heavens, fill enemies with terror, effectively slow down time, conjour magical barriers, bind spirits to their will, make their friends fight longer, harder and weaken their enemies yet they are as "mundane as every other shmoe" because they can no longer fill up a hit point bar?
I get that you liked playing a healer and despite being very in favour of this system, I do have symapthy for players who feel their role has been sacrificed in the interests of over all gameplay design, becasue quite frankly it has. However I do believe the system employed will improve the combat of the game significantly. I'm afraid its a "greater good" type of thing.
Unfortunately i read the post and it still didn't allay my concerns. While my mages were able to heal in past games they also were able to rain fire down on enemies, (and all the other things you point out), but now, with them having spells that do the exact same things tanks and rogues do (mitigation of damage vs regenerative prowess), they seem a lot more mundane. I had dedicated healers, but I also had damage dealing power houses who didn't have to focus on regenerative prowess and used 'heal as a backup thing' in case potions were on cooldown. Now combat is scary, like doing a highwire act with no net.
Someone else's experience in the game (even a 7 year old) doesn't help me relate to what my experience will be.
And, ultimately, i guess I'm just angry that I feel like they've crapped all over my favorite class.
