I settled on Rogue too, after playing around with Druid and Barb. Running a flurry with poison build at the moment and enjoying it. Problem I have is there's almost too many ways to be effective, whether you want to do ranged or melee
Haven't played much of necro get, saving that for season 1 as well so feels fresh.
Feels like the sweet spot will likely land somewhere in the middle? Probably want a nice balance of content type to give it the best chance of flourishing. From a modding point of view I think it always comes back to that clear ruleset that's consistently applied... The tricky part is actually doing it!
I'm happy to get involved, modded a couple of subreddits over the years.
I've got a similar philosophy to you to be honest, nothing too heavy handed, have a clear set of rules everyone can understand and only getting involved when necessary.
Edit - forgot to mention, I'm in Europe so can help cover that timezone.
I'm happy to get involved and lend a hand. Definitely want to help the community grow over here!
