The arena is definitely a moba style game however the game is a sandbox mmo similar to eve at its core. 99% of the heart in the game is crafted by players and when you die, generally you lose anything in your player inventory. So it's like eve online combined with Diablo. The progression of skills is very intense and takes a lot of grinding. You have a different skull for just about every piece of gear. Your abilities actually come from the gear you are using and you have a very wide range of abilities to choose from. Guild also own territories, similar to eve corps owning star systems. You can lose territories to other guilds by losing 5v5 battles that are called GvG our guild versus guild. There are also monthly resets on territories and those are the times you see a lot of large groups taking territories. It's a very cool game with a lot to do, but some peopledon't like the sandbox environment
