I miss seeing Jona on siege (although my shield has stayed pleasantly intact since his ban), but this and most other DTV drama could be fixed with one simple change:
Restrict the DTV game mode to <lvl 31 characters.
DTV should be a place to learn cRPG combat mechanics and/or slog through the peasant grind without being 1-shot by all the lvl 34+ tryhards at every turn. It should NOT be the fastest and most profitable way to grind your way to being one of those lvl 34+ tryhards. I got Gen 16, lvl 34 almost exclusively on low-population Siege, which certainly wasn't the fastest route (in fact, it's probably the slowest route) but it was a helluva lot more fun than mindlessly overheading bots on DTV. It truly pains me to see NA DTV populated with all the former NA Siege regulars while NA Siege sits empty. Any one of them would tell you that siege is more fun than DTV, but no one wants to sit on an empty server waiting for people to show up.
Jona doesn't exploit anything on Siege (except that ridiculous Spammaster's Staff sometimes), so he won't ruffle any more feathers if you just make him play there.
