I'm super-busy (TM), but a few thoughts:
- Making repair cheaper wouldn't be a bad thing, but I don't think addresses the root issue here. Sure, if you avoid a fleet wipe (as is implied in having anything left to repair), then refleeting costs can be substantially lessened. The assumption here is that fleet wipes are a fact of life for a significant number of playstyle/scenario combinations.
- Making refleet times themselves shorter isn't the primary goal; as others have noted if those were reduced to zero (a trivial thing to accomplish: 100% resource refund on death) the game would just become massively easier as the player's max defensive capability would never really decrease for a substantial period of time. So unless the AI had some kind of overwhelming sledgehammer (that certainly does happen in some scenarios) it would never get through. I don't think addressing the refleet-time issue is worth that kind of degeneration.
-- That said, having command stations give a modest resource cap increase, and FS cities give a substantial cap increase, would be worth trying.
- Rather, the primary goal is giving that refleet time a fun purpose. I tried champions, that only worked out for some people (I certainly intend to revisit various aspects of champs in the future, but that's a bigger problem to solve than this).
-- Reclaimable scrap would be a step in the right direction, I think, as it would give the player something to do that is directly related to shortening refleet time. But it probably wouldn't be a large enough step in the right direction.
-- Having the AI say "the player just wrapped his fleet around a tree, time for a wave" or whatever would certainly help, but I strongly suspect that many players would not like that feature. It could be a lazy/non-lazy thing (or separate from that), but I'm not sure that's the way to go yet.
-- A similar deal where both you and the AI can reclaim and the AI uses its reclaimed stuff ("Ooh, shiny!") to send extra attacks would be more reasonable all-around, perhaps, as the player's getting a buff (extra resources from successful defense, etc) at the same time.
Anyway, gotta run, just wanted to explain where my thinking was at the moment.
