So I guess the next vote will be on this variant:
SM escorts stay as in BFG R, costing 40, 40 and 45 points,
RSV's are identical in every respect (including Ld) to escorts in BFG:R Imperial Navy list ?
It seems to be more or less accepted, and offer probably the only reasonable compromise between keeping RSV's and making both types of escort viable.
Letting SM fleets use IN models as their escorts (Cobra as Hunter, for instance) would just be a counts as rule, leading to having same ship with different stats in two fleets. Sometimes in one game. Can lead to a misunderstanding.
