4:12:1 Double Day + Bulletproof IC has an EV of 41.76%, way better than 4:13 Double Day (26.40%). So, how early they can be killed is kinda important. A 1-shot BP IC won't add much, and the biggest benefit is on whether they are alive at mylo, but it's not inconceivable that a partially BP IC with some other abilities could get the EV up to a reasonable number.In post 654, callforjudgement wrote:Add an Innocent Child who cannot be killed normally until mylo to a regular setup with no killing/protective roles and an odd player count, and unless it's a strong player, you'll actually have very little balance impact whatsoever. It's nice in terms of helping the dayplay but it doesn't change any of the nightplay dynamics.
This isn't exactly the same, but the general principles are similar.
(This is not an endorsement of this particular setup, which has other problems. Just some drive by maths. )
