I've given every class a try, and I've come to like those two the most. Simple as that. I find them to be the most useful in conquest, as you are able to move across the map with great ease.

 

Ohhh that is tough, but probably Infiltrator as I will be keen to get my Wheeljack Chassis on!
...But I will probably have to save up Energon for that... so probably the Destroyer customized with G1 Optimus parts!

 

Scout/Infiltrator, it's been my favorite since day one of WFC. I used to like all other classes equally, but I'm really liking the Titan ever since I played the FoC demo.

 

I do well with every class, but I think I will start with the destroyer class, max that out so I can get Ultra Magnus, then it's off to the scientist, then the titan and Infiltrator
