@Vereesa: The context is 'there is actually a group heal' in game and this threads title is a wild, hyperbole lie. You just don't get a base, single target spammy heal. They got a ranged revive (and potions that can do that) and mages also get a group heal thats tied to the focus mechanic, it's designed to 'turn the tide of battle' just like other focus spells.
That's been pointed out multiple times in this thread, actually, but folks seem to keep ignoring the living crap out of all that so they can argue about why the games doomed for not having healing spells. Or how not having healing spells doesn't doom the game. BioWare forums WOOOO.
-edit-
@n7stormrunner: First off, as has been posted there IS HEALING. Just not spam-healing (and yes im talking about spells). The reason for it's removal, as has been stated is because we no longer regenerate to full health after EACH battle. That's it, we don't auto-heal to full after battles thus having a heal spell that could get everyone topped off after each battle if it's not limited would put a giant wrench in that design.
So now, instead of spamhealing they have 1 big group heal that's tied to the focus mechanic (but still requires mana). You can't use it all the time as you need to build your focus up, but it still exists and does, in fact, heal people. Folks have posted this multiple times in this thread already including my self. Mike confirmed it, on twitter, yesterday.
And that, right there, is why they do temp HP. It's like healing, with out having a 'direct' effect on after battle health totals. You can build up temp HP via guard, but your base HP wont be effected by it. So battles that tare away at that mean something. Potions are heavily restricted to ensure you can't carry hundreds around to just full heal after each battle if your super rich. A Dev actually made a big ol' post in here talking about that.
