1 new healer
SCH changes so the kit doesn't fight itself
Female Hrothgar and male Viera
Hair and hat problems fixed for Hrothgar and Viera
Ultimates and Deep Dungeons unlocked for BLU
Trust system in all pre-ShB story dungeons
Prae and Castrum changed into solo instances, MSQ roulette changed to have all mandatory story dungeons in it
50/60/70 roulette gets better rewards so it's worth doing more
Meracydia
