That wouldn't give captains much use, if you think about it. Sure, the boost to training might help initially, but that doesn't make captains much help in the long term. If you manage to keep your unit alive until the end of time, then that means a long time before the end of time that captain will have absolutely no role, because you'd probably get to max training anyway. The same goes for all the other factors that have caps that can be reached fairly quickly (cohesion, mainly). A morale boost would be nice, but it would have to be a passive and persistent bonus.
The thing I want to see with captains is some sort of persistent usefulness. Right now they do give bonus to leadership, which is...good and all if you're a marshal I guess, and a little bit if you're just a normal noble TL. But by the time you get to leadership 100%, your captain's not going to be much help, and he'll be what, +30 at best? That's a stretch, by the way. That's also assuming he lives that long. Instead, I'd like to see a slightly improved initial boost, but not so much that it's broken. It's hard to balance out something like this, but difficulty is no excuse for reluctance to try something. Usually I'd be reluctant to make any changes to something that isn't insufficient already, but there could be something done to make combat a bit more detailed.
Seriously, look at all the pretty features we got, and then look at our spartan and dull combat system. Yeah, maybe some people are genuinely impressed by the BM combat system, and maybe some people say simplicity is a good thing. The strategy is satisfactory right now. Maybe some AI tweaks, sure, but on the whole there's nothing lacking in terms of the combat system as a means of providing a strategy game. But there's something I can't quite put my finger on that is very bothersome about how BM is right now, with its flair and fanfare in many areas, yet something about battling seemed strangely boring. Of course, some people might indeed find these battles the most exciting things in the world...And to be fair, the combat system has been changed a lot. Still, for some reason this game recently has felt to me to be something akin to me buying Starcraft, then getting a bunch of patches that gives me more diplomacy actions for multiplayer, as well as a complex resource sharing system, a morale rating that determines whether my SCVs will actually work, actual Harvest Moon like farm sim in-game where I have to raise crops and livestock to supply the food for my marines, a full-blown economy system that incorporates every contemporary style of economics, etc. And yet I find that the only changes made to combat are some bugfixes and maybe a few balance changes.
Then again, it could be said that we shouldn't fix things that aren't broken. For example, if I were allowed to recruit heroes in SC then it wouldn't really be SC but more like WC3. I wonder though, would making changes to a thusfar mostly cosmetic part of a unit cause this not to be BM? I'm not sure. Has the captain always been intended to be more or less a roleplaying device whose name is randomly generated from some list and who gives a passive leadership bonus, most of the time which is pointless? I guess if nothing else it helps people who can't think up even one name, or don't want to, have a name to write down in their roleplays, or other messages.
