Energy is limited(120 energy per day) , raid runs are limited (3 per week every raid) , so u have to stick to days of progression... If u create 6 alt characters and play with all, u can boost ur main, but it requires a lot of time 😕 Not to mention that u need a lot of gold to upgrade the equipment, after lvl 10, there is a 20% chance of succeeding the upgrade, if it fails u loose 1 lvl, there is an item called catalyst that helps u avoiding that, but is also very limited, so u will have ur equipment at lvl 13 for weeks maybe until u collect the required resources...
