Are you comparing Almughavars to the Romans? If so, he was Superior and Elite Drilled Impact Foot.I think there is a world of differece between drilled Superior Off Spear and undrilled average impact foot.
True, and I tried to play the maneuver game, but in the end, the fight is going to happen in the open vs Heavy Foot. He's usually not going to enter and, because you're not impulsive if you 'could' end in terrain, you're not going to suck him into terrain.The Catalans are a very solid force but you have to believe in manuver and not head on clashes. There terrain is for where you fight through but manuver through.
What kills the Medium Foot IM(very Humble)O is the -1 for Cohesion Tests for losing to HF in the open. From what I've seen, if you lose a melee you usually get the 'did 2HPB' penalty. That means Superior troops will pass the Cohesion Test 56% of the time. But Medium Foot will only pass it 42% of the time because of 'losing to HF.' That difference is pretty significant.
When you factor in that most Almughavars are Off. Spear, this becomes a cascade effect because they then no longer count as Steady meaning you're down a POA in melee against most units. Now you're passing that Cohesion Test 31% of the time. So they're just too brittle.
(Yeah you can put a character with the unit, but there's not enough to put them with every unit that's going to be engaged).
I floated an idea to the local veteran, about suggesting tweaking that modifier. I get the idea that HF are just going to push around Medium Foot, but I think representing it in the Cohesion Test isn't right. I suggested swapping it out for a 'tie breaker POA' in melee. Basically Steady HF in the open fighting MF get a POA if there are no other net POAs. I suggested this in conjunction with the idea for whatever gets done for the 'barbarian POA' that is being talked about.
I also think that impulsive units should be something you can suck into terrain. Something like if a unit is in the open and evades, the impulsive unit still has to test to not charge and may end up charging into the terrain.
