Really find it hard to believe that was the sole reason for the kick. Seems that there must have been a contributing factor such as continually pulling off the tank due to poor threat management (with higher gear), exhibiting an elitist attitude conserning the low level of gear of the party, pulling for the tank just because you can, or as a tank tearing off like a rocket because you really do not need an excessive amount of heals.
I cannot think of anyone that WANTS to work overly hard at capping thier valor once you have no need for heroics gear, or obtaining their initial gear upon leveling to ninety at lower gear levels. Having a player that overgears the content only serves to lower the chance of a bogged down run but some players have attitudes that are "too geared" as well.
Not saying this is you. Just food for conversation.

Look at your statement. "I would make the other dps feel bad".
Was this because you came to them and would not help to bring them up to your level of play or was this because you TOLD them they were not at your level of play?
