LOL I have no problem getting revered with an opposing faction if they wanna do an insane style grind. Why would I?
It doesn’t have to come from quests, just mobs that are the main antagonists of each race in their starting areas / leveling path. I.E. Kill Dark Iron dwarves around / inside Blackrock Mountain to get friendly with Dwarves…
EDIt - I would say you can’t come inside at loathed, you would be Kill On Sight just like now. You would have to work your way up to be let in. I have to admit I miss EQs faction system. Especially if you say were able to go in to the city and everything was fine, till you ran into the paladins on a different faction system and they outright slaughtered you
