why Towers feel bad / suggestion for improvement

Towers feel bad because nothing exciting in the tower map itself.
Feels like a chore and a waste of a waystone

My suggestion add a mini boss guarding the beacon.
When you beat the mini boss then you can activate the beacon. When you activate the beacon you choose a reward.
