While the recruit anywhere Wardens and Lord Wardens are a welcome boost for MA Man, I don't think a bless strategy can be based on them. If nothing else than because the moment you have any decent number of Wardens massed, they become a pain to bless with only H1 priests. Main aspect of the Wardens now in CBM 1.6 is that the Lords are recruitable anywhere, as the Lord is a potentially decent thug chassis at a cheap cost (that may be worth a few X4 blesses). But he never got used before due to being cap only. (and so never got recruited ahead of cap mages)
Possibly a bigger boost is the increase to 25% on the second Crone random, as that increases the chance of getting those critical A4's (meaning you won't need an A4 pretender just for Air boosters). Would still like to see it at 50% though
And I second Hoplosternum's call on the Knights of Avalon. I brought this point up a few weeks ago on the IRC. The unit as it stands is pretty much pointless, as it will never really be recruited over the regular Knight. But if given a hoof attack, like most (all?) other heavy cavalry in CBM, then they suddenly become useful.
Hard to think these additional changes would overpower MA Man, since even with the recent CBM 1.6 changes, they still find themselves lurking at the bottom-end of the MA food-chain.
Edit: Just noticed the Knights of Avalon now cost 65 instead of 75 in CBM 1.6. So that increases their chances of being recruited. Still think they should have a hoof attack though
