Hi there and happy new year!
Morts I think the FS for rear support for pikes could differentiate Sp and Pk nicely, if Sp got +2. I too like the fantasy support values as they tone down the combat. You may catch the drift that I think MA may be too bloodthirsty for my taste!
The graded cavalry charge sounds feasible, tho perhaps the Cv and LH might have Shooting to offset their loss. This would mirror our view of their ancient role too, maybe.
In the murky Dark Ages I don't think the lack of differentiation of support matters much - just the scrum of the untrained and unwashed! For the Roman acies support formation, for deep pike, foot sirmishers with German cav and so on perhaps an across the board bonus for "Compatible Troops" or some such. "Deep formation" doesn't scan for the cav runners...
The mixed spear-bow units for the LIR look lovely and worked nicely the other day in my single hurried battle. I have altered the missile rules a bit as they are too overpowered.
I made a mistake - interference from Justified Ancients that I'm looking at now too. +3 would be too too much, agreed!
I am hung up on evasion rules and will continue to thrash them out! Worked nicely in the last battle with the Roman skirmishing horse. Units can evade once per turn, and are caught on the hop and normally destroyed if caught. Evade as a skill/characteristic might be free if FS<3, 1pt if 3+.
Your unattached general rules are neat and would work fine for combat heroes, tho I still like the addition of skills for other personality types.
I play DBA in a modified form, tho find HoTT designed for a different idea of fantasy than that to which I subscribe: Arthur won't be ensorcelled in any game of mine, and if there's no MU's, why clerics etc etc. I am tinkering with using some of the mechanisms from Basic Fury in MA, found on the Ambler Gamers yahoo group, as they enhanced my DBA games greatly. Except the missile rules. Which sem incomplete.
I do recommend you pick up a pdf of JUSTIFIED ANCIENTS on Lulu - the cheap rules are fascinating and tho quick play manage a lot of interesting concepts. I am trying out various rulesets to find the best for my liking as I finish painting the last mountain of barbarians for the BIG CAMPAIGN. Again!
