What unique mechanics do you think could be added to existing or future UU's?

Punishing your enemies by existing could be seen as anti-fun. It’s hard to explain but it can really throw off your enemy build order and apm so that just isn’t fair at all.


Thats probably why people hate laming and tower rushes too. Plus this bonus generally seems op and would be an auto pick every single team game.

I will like to see poison arrows unique mechanism.

Yes but tower rushing has its countermeasures. You can’t countermeasure a global omnipresent cost increase aura that lasts the whole game just by the civ simply existing.
