So find a place that's not guild-run? You can ask what's-her-name. Starling.

[ Tim knows damn well her name is Frances Starling, but acting this way is basically turn upkeep. ]

Maybe she knows a place that you can practice - not to fight, because that's for guildies, but just so that you don't hurt yourself. For now, I guess if Jay said it's okay, you can do it in the bar. I'm still carrying my own orders.
