Bob, in World 14 the group I was part of had 9-ish main fighters + 5 people who were willing to join when we were outnumbered (this includes foragers, hunters, a miner)
During the largest fights even, we only had 2 (TWO) b12s, only because we literally couldn't afford the steel. Most of the time we were running with stolen b12s. We could barely gear ourselves with armor. Some of us were running around in bronze still.
I myself chose to use a sword with shield for as long as possible even though I had the 3rd highest stats most of the time.
You know damn well we ended up having to go 1 vs 3 factions that world (because I cried about it all the time) and everyone was calling us the noobs for the entire world. We're the first ones that used jugular, and we didn't complain when it got nerfed, we were happy, cause it was dogshit free wins. Half of us didn't even have oppknocks in our decks, it was retarded.
We were still winning fights and losing fights regardless of how many b12's we had even after jugular got nerfed.
My suggestion still doesn't affect your newbies spamming one button when they outnumber another group. It only seeks to balance and make more things reliable, not just one weapon and one button.
