For season 8, I understand we want boss power to feel good and amazing. And I agree it should. But currently we are stepping into the realm where, every build is essentially building around boss power instead of actual build around our own character skills.
Boss power is super cool and fun - but it is borrowed power. I don’t think building around borrow power is a good idea overall.
I think S7 witch power is at a decent balance. Maybe tune the boss power down to match the witch power would be a good start.
It should not be useless like S3 construct at the beginning (which was brought up in power later phase of the game).
The glyph leveling should be seriously looked into, as current pit scaling, I am not even hoping to max out glyph anymore. But I think should allow everyone to at least get their glyph to 80 with time put in .
