I disagree.
Played 3 weeks of Mabinogi and quitted.
The combat is nice and everything, there is no tank concept, literally has to calculate to dodge and not take damage, it takes skill to actually play, but..
Quest? Lore? Aesthetic? PvP? RO (Pre-Renewal) pretty much wins everything.
The game is pretty much Pay 2 Win.
OP Paid Pets, OP Paid Equips, OP Refines.
You can freely rebirth and get real strong simply by paying too (Without level req/Age req).
The quest is repetitively boring, Hunt 10 Giant Hornets, next,
Hunt 10 Werewolves, next,
Hunt 10 xxxx.
All against recolored mobs.
Wtf? The mobs aren't even that interesting tbh.
If anything is to be better than RO, probably it might be SEAL/TERA/WoW.
but their quest system is as terrible as other MMOs.
Hunt 10 xyz.
Hunt 15 xyz.
Diablo 3 is getting better with the recent patch too.
but still imo, RO still is beast as its quests is done better. (Other than Eden ofc.)
