There are no classes in this game. As the player learns abilities and chooses items, the player creates his own class.
Since the player decides his/her own class each match, the gameplay is dynamic.
Because of dynamic classes, there is no "best build", as players must counter each other in order to win.

There is no chance involved in the game.
If you attack someone, you will hit. Critical strike, dodge or block chances that usually exist will never be a part of this game.
This is what should be called a pure skill based game.

Experience is added as time goes by. Thus, every player has the same amount of experience no matter of his stats.
Kill stealing is thus not an issue.
The game will never be pay-to-win. Items with different appearances could instead be a valid option for purchase in the future.

If you die, your waiting time will depend on the distance to your spawn. You rarely have to wait more than 3 seconds. If you are close to your spawn, you will have to wait longer.

A server can be hosted by anyone.
Any item, ability or setting can easily be altered by changing values in a text file. This works in real time.
If a player wishes to host a server that makes the character move at double speed, and that the only ability available is the Fire Ball and that it kills in one hit, that can easily be done with this system.
This also allows the server creator to "fix" imbalance.
You can also make your own maps easily with a map editor.

The in-game GUI is minimal to keep the player emerged.
You rarely have to look at the GUI whatsoever.
The player health is always displayed right above the player in the 3D world.

Friendly fire is always on. This limits ganking. If two players attack one enemy, they have to avoid hitting each other.

Tactics are crucial. You have to consider team mates, enemies, strategy, strengths, weaknesses, etc.
