Need an opinion regarding my upcoming mechanic Character creation

BoF aint that important seeing as how the new system where you'll want a 120 Cygnus is due in a month or 3. The Crit ring is something you can't get any other way (though I think KMS had another event with Chaos patch), but MW30 and SE30 you could get from other sources. MW30 might even fall in price at any given time. Tricky.
