Tera was kinda worth playing in vm4-vm9 patchs,probably even before vm4 but i wasnt playing the game at this time so i cant tell
i quitted the game on vm9 but honestly,a game where getting your bis have nothing to do with your skill level but only by insane grind,luck & REAL money is a no no no NO
But i can recommand FFXIV,you're trully rewarded for what you do in endgame unlike tera ,you can play all class on ONE character and there a tons more of content overall,the only flaw compared to tera is the gameplay
