They do a free trial from time to, erm, twice since release I think, but perhaps may again at some point.
Levelling flies by, too fast I thought.
You can die easily enough, this game doesn`t mind throwing in pointless one shot mechanics or perma-stun fests, but if you go afk, just pick a safe spot to stand, there are plenty (although not always safe, I recall some thief afk near mobs in southsun shore, where folk ran past pulling mobs & it just kept dying >
).
Quest wise, it`s weird to explain. It`s more a sort of explore when you can be bothered, wander into some area & an event may start/of started. You kill Nth amount of things etc, then wait to see if another starts, if not, mosey on by.
