Q:
I want a refund...
… okay, good bye!
You won’t get a refund because you are bored with it.
… I end up having to do them a couple times just to level. in short, this games turns out to be exactly like every other MMO where the things I do in the world dont matter at all because 2 minutes later the centaurs will be attacking again…
If you only stay in one small part of the map of course you’re going to see the same events happen again… why not try exploring a bit. I have rarely ever had to repeat an event (except across multiple characters). The only event I actually repeated on the same character multiple times was the firefly/mosquito one in Caledon Forest. And it was separated by real life days.
The centaurs want to take over certain areas, so obviously when they lose, they will gather up their forces and try again. I mean one of the centaur chains was even used as an example multiple times in interviews/videos, about how you can push them back to their base, but they will eventually build up their forces and attack again.
I doubt you will be able to get a refund at this stage, as you’ve obviously already used your access code and you’ve already played the game for a couple of days.
But you’ve come to this conclusion at level 20? I highly recommend that you try it a little longer. Dynamic events actually become a lot better, and dynamic combat becomes much more important once you’re out of the starter zones. The higher level zones have some pretty impressive dynamic event chains/webs. Don’t give up too soon just because the starter zones don’t overload you with the most impressive dynamic events right then and there.
