I played CNJ to 35 in Beta 2 and the first instances are snooze mode when it comes to healing. Once you get to Toto-rak and Haukke manor though, spamming cure will oom you pretty fast. By 35 you have several tools for healing - Cure 1, Cure 2 (which has a proc for a free cure 2, I can't remember how to proc it), Medica, and Stoneskin. Most of the time though CNJ will heal in Battlepriest stance and act as a extra DPS'er, healing in Battlepriest stance or weaving between them as needed. The class can be min maxed pretty far if you are willing to do so.My CNJ (I was Svieri for those who might have grouped with me) impressions:
1. DPS was horrifically bad compared to real damage classes. It does get better with Stone 2, but it's still awful and as Pyros mentioned above it's even worse because you literally only have one spell to cast. I tried leveling up THM a bit to see if it had anything to offer CNJ main, but it really does not. You get Lightning, but it costs too much mana to be useful most of the time. I guess THM spells are all designed around the MP regen from ice, which makes them suck ass for other classes. Aero needs to be reworked again, because it's worthless outside of a couple irritating solo-instance quests which end up with you Aero-kiting for 10-15 minutes to kill something.
2. I know next to nothing about the 'advanced' classes (my understanding is that you don't level up WHM as a separate job, you just become a WHM at a certain point as a CNJ?), but I was really disappointed with the synergy between the basic jobs. Other jobs can get some nice stuff from CNJ if they level it to 12, but CNJ gains practically nothing from the others, just a bunch of WoW-trinket-style short duration/long cd buffs. Thaum was very disappointing, as is the lack of a red mage's existence. Pugilist was the only job I felt had any real potential as a secondary.
3. Healing is EQ1-in-1999 bland. I literally just spammed Cure 1 on the tank almost non-stop in dungeons. There was practically no risk of running out of MP ever unless I nuked too much. Strangely enough, healing with a gamepad was also vastly better than healing with kb/m. For one thing, when it's at its dullest, I can just recline in my chair and press triangle over and over (first thing anyone playing with a pad should do is switch the triggers to toggle mode). When I felt like throwing around dps though, it was really nice to be able to temporarily target a mob for one spell and then have it revert back to the tank; same thing for switching to heal a dps who decided to stand in the fire. The only interesting mechanic in the first 3 quest-dungeons was the blob fight where I got to kite all the shit around with heal aggro while everyone else set us up the bomb. I just got to the Ifrit quest a couple hours before the phase ended and didn't get to actually do it.
4. I really, really hate the 2.5 cast time/GCD on everything. The pace of combat might not be as bad as it was in 1.0, but they still need to address it in ARR. Incidentally, I don't know if this is a bug or not, but did anyone else notice that using Sprint in combat gives a massive amount of spell haste? It took my 2.5s casts down to about 1.6s.
In the end, I'll probably play a CNJ anyway despite all of the above, if I buy the game. I always duo with a friend so I'm not worried about the dps sucking ass, except in the solo instances. The downside of NOT having a CNJ/WHM available 100% of the time is too great to not have one of us pick it. I'll definitely need to see a good bit of improvement in the mechanics as phase 3 continues before I would pre-order the game, however.
Edit: For people thinking about the PS3 version, I read that everything kb/m related works just like the PC version *except* that you cannot currently get a PC-style hotkey bar instead of the cross bar. I assume that will be fixed at some point, since the cross bar is a new development. Personally I would be fine with just a USB keyboard plugged in and "direct chat"--which makes everything you press on the keyboard go straight to the chat box--turned on, and no mouse at all. The gamepad controls are very well done once you figure out the intricacies of targeting.
I agree the rework to Aero was stupid. Dots in general need their Dps increased by at least 100%, they're all useless at this stage. I'm not sure if you got Fluid aura, but it adds some more DPS dimension to the class. Stone 2, Fluid Aura and the old Aero was less boring than mashing 1 over and over.
You have the option to convert from CNJ to WHM at level 30. It involves levelling a sub class to 15 (I think Gladiator for WHM?) - There is a downside though. CNJ can use abilities from any other class as long as it's shared. WHM can only draw from their two classes (CNR and GLAD)
