Oh this is easy fix make explodey jar carry in arms require a certain amount of strengh to carry it… say 15 strentgh. And then every strength over that just increases movement speed.

Next make certain boss and npc immune to certain weapon grade so your forced to upgrade your wears. Then next start to introduce passive farming with thralls and automation recipes maker like stastifactory.

Also id redesign how armor works is depend on weapon gear level it can do multiplyer more or less then depend on gear is being worn.

And then lastly add in a signature downed status like in gear of war mechainc… add in mortal kombat fatalities. To finish off your foes.

This will revive people love for the game.

Also by using a down state people will have one minute to truely finish off an npc or player. An added bonus to why this mechanic would be helpful. What if you didnt want to kill a certain npc to be bonk later … this can help with it.
