An idea just struck.
What happens if an inf stand that is defending(=not charging) and supporting isn´t supporting in the way of the WM rulebook, but instead supports in the way of the WFB rulebook?
Meaning: a supporting stand will strike in the ensuing combat phase just as if it was in base-to-base contact with the enemy.
So if the supported stand is btb, the supporting stand will get to use all its attacks aswell.
This (may) mean:
No existing rules (but inf support) have to be changed.
No "they get to support before they realise they are dead".
No "digging in". (but I like this idea).
No "inf actually CAN run down retreating riders".
But a big YES to supporting the rules.
Meaning: almost all existing rules regarding charge, flank, pursue, so on, adds/deducts attacks to the ensuing combat phase, all but support.
With "support" meaning "extra attacks", it will add to the rule set:s intention.
This just came up while wearing my sofa down on this saturday evening, so there is no playtesting done or discussion held with fellow warmasters.
