I personally like Bumblebee for Autobots, and Barricade for the Decepticons. Bumblebee for his room-clearing Shockwave ability, and the deadly Dash, then melee combo. I love his Car-mode machine Gun too. I like Barricade for the same reasons I like Bumblebee, the Car-Machine gun and Shockwave are both handy, but I like Barricade's Barrier ability over Bumblebee's Dash. Barrier is really useful for sheilding yourself when reviving a teammate, and if you're taking on a Machine gunner, or a titan. Your Favorites?
