On like every edition of classicus you hosted you promised new content and updates yet never brought any into the game, same with thronia so far, dont really know about Oldera, but you also made some bad picks when you promoted a certain of people to GM,
As for frozemoth you shouldnt make it immune for vis lux, you could lower the damage of vis lux on Frozemoth aswell the exp/loot, but making it immune for lux would just ruin it, its a nice place to chill at and exp without doing to much of a work, but on last version it was to OP way to much profit and exp was sick aswell. So you should be able to exp with 2 sorc or more there using vis lux but try balance it so sometimes you go profit and other times you dont, now it is 200% sure of profit.
