It's quite rough and immersive: I liked it! Audio and visual effects feel great (bullets and arrows flying, artillery and magic attacks, characters screaming in pain or yelling when using a skill, fires, smoke, explosions). More below. Mechanisms described here : https://imgur.com/zf8pmte
(I didn't prepare any PvP build, neither did I farm gear for it. Fight wasn't very balanced: our group was stronger)
-----------------------
Lot of possibilities thanks to the classless system, allowing to specialize in one role (dps, tank, healer) or to create mixed builds (melee/ranged, tanky mage...) or to focus on CC/debuff.
Buffs are available (food, drink, pots), also healing and mana pots
Weapons offer various CC, status effects and debuffs, AoEs. It's easy to get interrupted, knocked down, slowed...
Lot of possibilities regarding organization, coordination and tactics (ingame voice, army chat, pings).
I wish that interactions with the environment were deactivated (trees, boulders, bushes...) and that roles could be set, also to be able to tag targets (with signs or numbers) and to have a build saver.
