@KingEroc1st That is excellent tweak man. I remember one time when they accidentaly made arena give You 100% of the normal experience and it was sooooo satisfying. Like it wasn't a matter of cheats, this experience was still earned through hard work and beating the crap out of arena folks but at least when starting a new campaign I had a way to train myself instead of having to hunt looters for months to come.
Also I would love to see retirement and importing characters mechanics from Warband. I tend to start new campaigns and make different decisions, see how things unravel differently but having to train your character from 0 every time is a bit tedious. Like I already have a few perfectly good characters, let me just use them instead of having to go through all of early game grinding again. I loved that mechanic in Warband and I had a few trained heros that I used to import every time I started a new campaign
