I'm not familiar with Durge, and I'm not against Durge as a playable character, but we already have a GL Bounty Hunter. Jabba has the BH tag.
So if you want to advocate for this toon, you'll have to make a case for a Separatist-specific version.
Sure, we can advocate for him as a Separatist GL but he'd still be tagged as a Bounty Hunter regardless. Besides, we already have 2 Jedi GLs (possibly a 3rd coming soon) and 2 Sith GLs so a 2nd BH GL should be fine, especially if he's Separatist which would make him a 1st for a GL.
You can watch his full fight in the Clone Wars animated series and read his Wookieepedia articles to familiarize yourself with him more: https://www.youtube.com/watch?v=wmJqgdaTArM
