The game is poorly optimized, dead, and heavily based on pay to play scheme.
Its not even Free to play when you have to wait to do the following
Fight (unless you pay with gold or get a membership)
Upgrade (unless you pay with gold or get a membership or a recharger pack)
Control Land (unless you pay with gold or get a membership)
Player Vs Player (unless you pay with gold or get a recharger pack)
Missions (unless you pay with gold or get a membership)

Everything is based on a pay to play system.
