Imo things really begin from lv65 and in vm7 patch they made ppl reach lv65 fairly easy and comparing to other MMOs, it's so easy to obtain costumes, mounts, special rewards through events, achievements.

Tera only have tiny issues that bugs users. All fixable though and all can be ignored too.
- class-gender lock. pretty much OP classes are all gender locked. But i was never bothered by it. Elins are small so it's good for PvPs.
- I have 2 Lv65 that went through whole questline. Though it's stereotypical, I didn't find it hard or annoying. Good thing is no repeatable quests
- But there are some quest dungeons that doesn't support instance matching and the quest won't progress unless it's 5-men dungeon.(you will understand what i mean when you are lv50+)
- flying mount stamina and fall when you enter a no-fly zones.
- movable UI. for some reason there's no UI lock nor a camera lock.
+ dungeon instance match, even if u don't have friends or guild, u can still find groups with this.
+ good graphics but also detailed options for graphic settings.
+ easy events for costumes, mounts, cool things.
+ pay to win is an option, but play to win is totally DO-ABLE.
