Oh boy, I came in here, read through the intro post, thought, some influence would be nice and I love scrappers! Then I saw all these long and well thought out posts. I don't have anywhere near the in depth knowledge and breakdown of some of these others. But I do know what I've found to be very fun, and it's not on the list.
Claws/Bio
An absolute blast to play. Claws is of course claws. Fast recharge and fun to play. And Bio is just so good. I'm constantly switching between the adaptations to fit anything that comes my way. My guy is a tiny little organic armor dude named Adaptabug.
My global is the same as my forum name, Zulgeek. Good luck!
