the most playable assault mech?

Hellstar either of them.

Most of the other goodies are "Heavy Class" Mechs. Stefani, & Caden

OEJ or the black Atlas.
They work for me. ;)

My vote..

A toss up of Declan Devalis or Andrzej Czupek. i love both of them and they both can Wreak Havoc on enemys so quicly that some people just can bounce back.. i have one 600 pt game where i ran Declan and Andrzej with ATV's. one opponent just quit as he knew that he couldnt touch them =)

Clyde Joyce (Hellstar) or Declan Devalis. My first choice would be Clyde.

Jung Chae is almost as good, but lacks the range and the Camoflague.

jung chae or any of the tian zongs are sweet

I would take either of the Yu Huangs. They are killing machines

well i do like declan, but i have also used, angus and seka for some good carnage.
