So, got several O5e campaigns going right now, and don't want to convert mid stream (or mic 0fe and A5e classes even if they are technically compatible), though I do plan to use the new monsters, journey rules, etc. right away.
Beyond that, the next time I start a campaign will offer to do O5e or LU with encouragement to try LU, and am also going to be working on finishing up my Homebrew setting specifically for use with LU (including new heritages and cultures and a list of what O5e archetypes I am allowing) to eventually run either a homebrew campaign or modified version of War for the Burning Sky.
