Had chance have a quick look at the proposed changes, and a couple of thing caught my eye.
TurretsDo they hit on 5+ against ALL ordnance that attacks that turn, or do normal rule apply (i.e. only vs one type per turn)? If the latter, that's a little harsh, even with extra turrets all round. The former does seem Orky though, lacking accuracy and co-ordination for sheer volume of cover!
Zzap gunsStr D3+2(Front mounted)/D3+1(side mounted) for cruisers/D3 for escorts?
Slamblaster aside, strengths as presented seem underwhelming to me, given the extra cost. If Zzap Gun spam is a concern how about a limit on the number ZG armed ships, rather than a surcharge. A ratio of 2 non ZG armed vessel/1 ZG armed vessel of each type? I.e. 2 cruisers to one with ZG, 8 escorts (any class) to allow a 4 with ZG's
Bad Moon escort upgrade+20?
I know it's a little late in the game for input, and I'm not sure on what's been decided behind the scenes, but please take these as an outside observation. If any of these points have been worked on, please disregard as approriate
