I think currently for skyblock players Lunar doesn't have all the necessary features so they still would use forge or badlion. These are some of the mods that would made Lunar forge such more appealing to all skyblock players and they would have no reason to play other clients.
-Dankers and Soupy are both QOL mods that add more features such as dungeon solvers, better GUIS, many trackers for skills and slayers, diana waypoints and a salvaging guard. These mods are pretty similar but I thought to recomend two as you might not be able to add one for copyright or other reasons.
-Dungeon Rooms Mod is a simple but very useful mod and I cannot play without it. The mod add secret waypoints in-dungeons allowing you to find them much quicker and allowing newer players who dont know secrets to find them.
Thanks for considering this I hope you take it seriously.
