Teaching GoW a lesson (you're right, you're right, we shouldn't let it cloud our judgement).
Still, psych warfare is important enough, and the outcome of a bold and successful move against them could be less troops heading for the front, and more troops scattered trying to defend an impossibly long stretch of land, out of the (justifiable) fear of another landing (don't forget the loss of scouting capabilities, and staging points for a sea borne assault.
What I was thinking about is using 1-2 galleys, to land a small and manueverable force of WC's (or maybe something heavier, if we can spare, but I doubt we do) to attack undefended cities, without the intent of keeping them (mostly 1 pop cities that would auto raze, like Port and the cities around).
The benefits are nill in terms of hurting their war-production, and we're to lose any serious confrontation with their troops while using such a small force, especially once even one or two riders come along. There is also the risk of Lego getting alarmed and choosing to intervene- but this is a question of when, but I think we still have some time before that happens, unless Lego has been preparing for it for a while... (perhaps Vox could help with that, hmm...), but like I said, the risk is minimal, the cost is small, and the benefits might be worth it, in the long term.
I think we all agree there will come a time, not so far in the future, when we'll want to attack GoW or ND. The first question is who's first (or perhaps both at the same time)? I'd say GoW first- being an easier target, as well as allowing us to close on ND from 2 sides (should RP fall) or from 3 sides (should RP, with our help, manages to reclaim their lost cities). Do we want to land soon, in less than 5 turns, with a small force, or we rather suprise them with a nasty stack at their doorstep?
I'd side with a quick 'in-out' assault pretty soon, also because we
need to get them off our backs, and throw them off-balance (or at least try to), so we could help RP save what little they have left.
