The 1st day I was able to get myself to the #2 position, if you were playing the campaign previously you got to keep your previous rank, mine was 10 I think.
I never had to use more than 1 battle energon to beat the bosses, so I had 100's of them, I started to use them to level up and further progress in the game, fighting more bosses and getting more medals. Id have to use at lest 50 battle energons to level up.
Then the game changed, the bosses got tougher and it took me more than 1 battle energon to win, I started slipping in rank big time. My worst was 130 or so.
Then I worked my way back, assisting others and maxing out my characters, my ending rank was 28 which im pleased with.
I know i put in hours and hours, to anyone that ranked higher than me, you obviously got nothing done at work for that week, because I didn't, lol.
I hope card trading in this game gets enabled soon, from what I understand its present in the Marvel game. I have at least 10 event hounds, an extra Metrolplex-4 and Optimus-4, along with a Prowl-4 and Mirage-4 that id love to trade for their alt forms.
