You really outdid yourself with the Lions Guard skins, they look great! Probably warrants a revisit to the battlegroup skins since they're so dated?
Most of the Guards ships themselves are just as dubious in effectiveness as the descriptions make them to be, quite gimmicky to make proper use of them.
Also, since the PD & LR PD lasers cost the same now, the LR PD seems like the better choice with it's superior range and decreased flux. Not to mention having 4 small pd energy is pointless. Why not remove one them since mining lasers fill the cheap option and burst lasers give the advanced option?
Also, the mausoleum shrine really made me emotional

. Your storytelling is getting better and better, keep working on that and SS might get close to the likes of Homeworld regarding plot quality.
