Up until the last month or so I really kept up with the game. Participated in pretty much every event, built my hands and so on, cant say I ever spent a penny on the game though.

Im not surprised its ending. Much like Raider said, all the events are the same, the cards you get are no good after a month and took forever to level up etc. Also they just stopped trying - the artwork and cards were all getting rehashed, there were lots of mistakes cropping up that never got fixed (Bumblebee cards called Shockwave, events about Galvatron just having Dinobot cards etc) and players were dropping off in droves.
