A thought that popped into my mind is how awful it feels to restart every encounter with IP stacking. Something that popped into my mind would be making abilities into combos so they still yield some tangible feedback/output but at a reduced effectiveness. For example sword of storms could be 2 smaller single target attacks leading to an aoe like it does now.
Theres a lot of possible ways it could be looked at but it’s just a passing thought and nothing more.
