There are no healers (aside from a Bard's AoE healing song(weak)), but everyone can use a Party heal scroll, which is rather cool. You'll get these as drops / rewards / vendors, the UI has a slot for you to equip them (default hotkey is Y). There are two ways to use the scrolls. The party window has a red cross next to each members name, if you click it, you'll use a scroll to heal that person. You can also assign a primary heal target so you can just use a hotkey (Y, or any hotkey slot you drop the scroll into), so that you just press the key and that person is healed.
Some other systems that are somewhat interesting-
Food: Eating food has a couple benefits depending on the type you eat; there are the standard types that give hour long buffs to HP, DEF, Evasion, etc., then there is a system that is based on Energy / Satiety. These foods give you a certain amount of Energy for a certain lvl of Satiety, you can have 5k Energy / 1k Satiety, the better the food, the higher Energy / Satiety ratio you'll get. All your skills will use some Energy, so you'll run out eventually. At max Energy you'll have like +10% HP / +10% Atk, but there are no downsides to not using that food. There is a Chef craft, and right now, you can easily get to the point where you can make 675/200 food, but you can also buy that food for 1sp (I think prices might change later...everything is 1sp it seems).
Souls: Every mob you kill gives you 1 Chaos Soul. These need to be "purified" in order to become the resource that you use to grant yourself a nice buff (5 different ones to use) on a 2min timer. To purify souls you need to be a town or camp, or you can ask another player to "co-op purify", using the CoOp version will earn each player more purified souls than using the default system in town (CoOp can be used anywhere). When you purify, each of the buffs get a certain number of Souls, not sure what determines how many each Buff gets though.
Leveling: There appears to be 3 ways that people can level, depending on what they like to do; Questing, PvP, Hunting. The quest path is the standard we're all used too - follow the Story and do quests at various places. Using the PvP path just means doing the arenas/bg's, you'll lvl up just as fast and the gear you can get is just as good as quest / random drops. The Hunting path sounds pretty boring, but it can be a nice change of pace from the other two. There are various hunting grounds throughout the world / lvl ranges where you can do repeatable quests that give you XP and Badges. These areas have normal mobs and elites, which drop the quest item you need (elites drop more). The badges are used to buy gear, the "green" gear is just as good as quest rewards / drops, while the "blue" gear is about as good Solo dungeon gear (but no set bonus, and not as good as Heroic Solo (I think)). I took my Guardian (Stormguard) into the lvl19 hunting ground (bunch of slutty cat ladies) at lvl21, made 2 lvls really quick (maybe an hour) while I had a double xp buff up). Getting gear via this path seems really, really bad compared to just running a Solo dungeon, so I wouldn't recommend it.
Fun game for what it is, though I don't like the movement system much. No free look sucks.
