Okay, I tried most classes and finished the first zone (LV 11) with a character, and did some quests on the new map, so I think it's safe to post some impressions, that I will update if I find something new or someone asks something. I was gonna do a Let's Play, but I would die of MMO quest boredom LPing this.
Good things:
Combat: Is great! Not perfect, but is light-years beyond any MMO, and most action RPGs too (I'm looking at you, KoA). All classes play very differently, most enemies require different aproaches to kill (at least when you are low Lv), and the boss fight at the end of the "tutorial" showed how great can this combat system be. They managed to mix very well the standard MMO skills with a great focus on movement, dogding, blocking and carefully timing your attacks, much like Dark Souls. I would really love to see this becaming the new standard for MMOs.
Graphics: Absolutly amazing! I'm not a fan of the art style, with all the world looking cute, colorful and "bland JRPG-ish", but holy shit, the graphics is the best I ever saw. I have a i7 with a Nvidia GTX 460, and was able to play of Ultra Settings, with no lag or FPS slowdown. I was amazed, the view distance is masterfully handled to seem unlimited, the textures are really high res, the models are great, each race & sex is completly different and there are different animation for each class/race/sex combination (watch and learn SW:TOR).
Bad things:
Quests: SHIT. And I mean it. This game was sadly made "by coreans, for coreans" and it shows. My quest log says I did 127 quests until now, and ALL of them where either "gather X", "kill Y" or "talk to Z". And they are made to hold you up; you kill 10 lions for their tooth, deliver the quest, then another quest giver ask you to kill more 8 lions for their mane... besides, the lv requirment for quests is way high! You have to complete all the quests in one area and then grind a little to unlock the next quests! And writers must be cheap in Korea, as all the quests have fucking walls of bland RPG text, 5 boring paragraphs explaining how it's important for Mr. NPC that you go and kill 12 boars for him...
Controls/Interface: They are trying something really unique here, mixing FPS aiming crosshairs and "mouse-fire" with a third-person action-RPG combat, so it's expected that somethings don't work well. Swapping between "fight mode" (your mouse is the camera) and "menu mode" (standard cursor for use on menus and inventory) is weird, having a radar and a mini-map on screen at the same time is dumb, and even if you scale up the UI, some things like mouseover descriptions and quest text still stay the same minuscule size, killing my eyesight. Also, somethings are horribly placed in the menus, like crafting is in a weird place together with the guild menu and battleground ratings...it took me almost 2 hours to discover it.
TL;DR: Great graphics, great combat, everything else is bland or bad.
Honestly, If you fused this game with SW:TOR license, quests and dialogs, you would have the definetly WoW-killer. The way it is, is just an elaborate tech-demo to remind us how PC-exclusive titles can look good if people put a little effort on it...I got a beta key for 5 weekends but got bored on the first one. The combat is really fantastic, but having to grind for hours to get to a new zone with new enemies is frustrating...especially since there are A LOT of pallete swaps mobs that fight the same way.
Here are some screens I took of the game, to show how goddamn beatiful it is:
Leaving the first area of the game.
