Change Lost Towers to Protect from Waves

I suggest changing the Lost Tower Map to a stand your ground and defend the tower. Have 5-10 waves after successfully defending the tower it stays lit. You wouldn't clear a map. You'd portal in right at the light switch.

I believe this would add a small variant of gameplay instead of every map being find all the rares. Lost Towers could also not require a waystone. This gives people a chance to farm some content when they are low on waystones.

Towers are "useless" in the way they are, just a nuisance.. I would agree to making a change to make them easier to complete.
Most people just dump their low waystones on this to run through them quickly.
Making them either a stand your ground or just a bossroom or something else that make it less of a nuisance would be a lot better imo.
