Played up to Palace Cellar @ lv20 after getting in CBT4, so I had a taste of the first dungeon but nothing more yet.
Levelling up 1-20 I felt like the game was a quest grind, and I didn't have too much fun playing it. I am glad there is LOS since it is PvP focused, but when I found out that my spells couldn't be cancelled if an enemy moved behind me I was really sad. I feel like if a modern MMO is going to be tab-targetting, then players should have to manually face towards the enemy when they cast spells on them. It just adds on another skill layer to combat in the game. Soo.. I would rate combat a 5/10. Good enough to play, but not amazing.
Class combination is an interesting thing. I myself prefer having many many classes(20+), but not through this class combination thing Archeage does. I feel like individual classes would be more fleshed out if they were built individually instead of this class combo thing. I've nothing really to comment on it. It's kinda cool, but nothing special either imo. It's really complex but sometimes you risk becoming a subpar version of what you really wanna be :<
Palace Cellar was where it started getting fun for me. 2-manned it with a friend and we wiped a lot on the last boss. I had a lot of fun, but the mechanics for the last boss fight were really obscure; I didn't know that walking in the water would put out the flame and that I was supposed to use a nulling potion on the boss to take off his buff lol. I think when the game actually launches I'll pick it up and play it again since I had fun running that dungeon. Hopefully, I will also do some other stuff and PvP when I get higher level after launch.
