I am loving this game for a few reasons, all listed below.
Just started playing 3 days ago and in that time have a 30 Slayer, 9 Priest, and 8 Warrior (I was sick all weekend on meds, what else can I say?).
I started with the Slayer just because I felt that is the class I would do the best with just to start the game. Its a heavy hitting, highly mobile, but only medium armored melee DPS class. Do not try and tank, or even get in the line of fire with a Slayer. You will take big damage. You have an evade on a small cooldown that lets you get out of the way of harm easily enough though so that is OK. Its a burst DPS class, where you charge your mp to use your advanced abilites. Build plenty so you can chain them together for a nice chunk of damage. Rinse, repeat, and go to town. This does change up when in an instance as you do have to focus more on staying out of the danger zone of being hit. I stayed in the middle of a group of enemies just a little to long yesterday after using my abilities and died pretty quick. A fun, fluid, big DPS class to play IMO.
The priest. I was a little hesitant about starting a priest up just because of how combat might work. Turns out it is quite fun, you get plenty of offensive skills, and while killing things takes a little longer then the Slayer, is very very viable for solo questing. BAMs might be tough to solo, but Ill talk about those later. I havent gone and healed any groups or other people with it yet, so I cannot comment there. Again combat here is very fluid and fun.
The Warrior. I wish I had started with warrior instead of Slayer. Just a blast to play as. Plenty of big skills. Damage skills that when in use reduce damage you take and an evade/aoe combo make this class a joy to solo with.
Cant comment on priest and warrior more then that as I just dont have the play time on them to be able to do so.
Found a guild quick enough. Some good people. Seems like lots of people have come from Final Fantasy 11 to play.'
BAMs are hard, cruel, long fights. Lots of fun, but require immense concentration and effort, but EXP payout and loot drops are massively increased as well.
Instances. Only played two as Slayer so far, but tons and tons of fun. The fights are very dynamic. You cant just sit and do your abilites then move to x, do abilites, move to y, and repeat. So nice to have a system that player skill matters more then where you stand.
Graphics - Damn this game is good looking. Environments are gorgeous. 5/5
Story - I havent been paying that much attention to the story as Ive been having fun with the combat. Seems solid but not great. 3/5 (so far).
Sound - Other then mounts are a little too vocal for me, beautiful. 4/5
Combat - Every class is unique and fun (so far). 5/5
Loving this game. Fully recommend it to anyone looking for a unique playing experience that is tired of same ole same ole MMOs. I loved FFXI, love SWTOR as well. Never been a big WoW fan. Loved the zone events in GW2Beta/RIFT (not so much the combat, but just being like, "Hey, whats going on over there?" and proceeding to plow over an event with a bunch of other people).
SWTOR story quality, GW2/RIFT zone events, and TERAs combat system would truly be a perfect game for me. Till then, Ill be on TERA and SWTOR for their respective strengths.
