My idea is like this:
Make dungeon D1 and D2 max level 60
Kimu is not even a challenge with an 80 toon, and ele 1 also drops at CG.
I know the respawn at D-Water is not ideal, but it's something.... I mean the dungeon pvp can be amazing and there would be a freeby boss to fight for on top.
Just limit the portals and make a rule that it's illegal for higher levels to move/summon in there.
Same suggestion I made a lot of pages earlier, but as everything in this post it got ignored
But it a really good idea.
And wouldn't matter to 80s since they don't need kimu or anything from d1.
And this is something even psevers are cable of implying so why not AGE?
