Butterfly's will be a great way to do redemption theiving. Levels out the playing field with non irons a little bit. Each one will be worth about 50hp+ per invent which will be much better than using sharks etc
This could work well for Clan masses. Organize your clan to use the hunter butterfly pots and just hang out and chill, buffing eachother. Practicing deathdots. Sounds interesting
Your idea of creating a community of people that willingly share butterflies sounds awfully alot like communism haha. Hoping that everyone contributes anonymously didn't work with the Soviets, probably won't work in a game sadly.
