The only thing I can see him doing is injecting HD into the RuneLite Client like how OSRSHD Client did, but refused to share code with Jagex.
I agree with Custom Dungeons for Wildy, we need to get out of "OSRS Content Only" kind of server and have some sort of custom content.
Even adding some sort of NPCs that drop some Boss items at a 1 in 32,756 drop rate would be something. Lol
