In these 6 months many things have happened in the game. He has already become a level 78 Warrior. Not only that he is also very close to leveling up. Actually not only his warrior Avatar, but he also advanced in his assassin Avatar and his mage Avatar.
His assassin Avatar already became a level 30, while his mage already became level 50. So with that you can see that he not only focuses on his warrior Avatar but he also focuses on his other avatar.
Also when he will level to level 80 he will be able to open his new avatar. Well, if he could only focus on his warrior avatar then he would already be over level 80 but he also focused on his other avatar and because of this, he still didn't level up.
