Fun to play but the reward system is virtually non existent. The extended the endgame by lowering the drop rate on items that would be easy to farm in any other game. Their system by which players choose how to play the javelins, the inscription system, are random rolls on random gear that can drop anywhere.
Meanwhile the better ranked gear beats out any inscriptions you can get. Wanna play a burning orb storm but get a legendary for electrical damage? Guess your doing electrical damage. The legendary drop rate is so low that your chances of getting a fire based storm like you want ... may as well play the lottery. Your chances are higher.
Player choice is so limited, you cant even get reliable store access
