For the wins issue: Some people, Like myself had played in the event before it was taken down and those event wins were counting towards the total wins. Also like mentioned above some people buy items to recharge their battle points to attack constantly. this also provides them with higher win totals.

Currently at level 53, have bought a couple of premium packs. Hit one Super rare Elite SHOCKWAVE.

Also with the event that was running before it came down for maintenance, super rares are able to be pulled as well. They have a slightly higher drop rate with the silver medal awards from the event. I had at one point 350 medals and out of the 350 used 1 medal = 1 card, I hit 2 Super rares, JETFIRE and ELITE OPTIMUS PRIME. so the drop rate is extremely low for super rares but it is possible.
