It is complexity on different scales though. ASL being a tactical level game and WiF being a grand strategy game, they have different focus.
In ASL you have a scenario and you optimise given set of assets vs the scenario objective for your side, information overload in the mechanics and on the counters. It is rather one dimensional on the strategic level.
In WiF you have a spectrum of strategic options and an economic component, but tactical combat is rather one dimensional.
Learning with MWiF is only advised if you want to stay with MWiF. You are playing a different game in the end.
“WiF is like sex: sure, it may give some practical results, but that's not why we do it.”
