I just want to throw my 2 cents into the ring, I played neverborn in M2E. I got into the game because of Jakob Lynch, and branched out to love Collodi, Lillith and Pandora. I owned every single Neverborn model and had most of them painted. I had stopped playing due to other reasons by the time M3E was announced, and seeing that 3/4 of my main-stay masters were gone or changed into a new faction I promptly listed them on eBay and resolved if I come back to the game I'd simply try something new.
Months later, time for release? I just ordered my Brine & Bones pack, and some Resurrectionists stuff. I'm excited to play the game again and I even have a brand new faction to collect, paint, and fall in love with.
So may I suggest... instead of having a toddler sized breakdown, take the change as an opportunity and learn to love something new.
Edit: I want to make it clear to OP, i really do respect his decision to learn and adjust his outlook based on what people have discussed here. The toddler sized breakdown comment is more for the guy who is quite obviously having a tantrum.
