I did some unit testing that surprised me and which I found interesting.
There was no cycle charging, just the initial charge, period.
I tested a greenskin giant vs a unit of hammerer. The giant is AP and the hammerers have a good armour. The hammerers are AP and the giant has no armour. Plus, the giant costs more money. So I thought the giant counters hammerers and costs more, it will wrecks them.
Yet, the hammerers won by quite a good marging. But the giant is known to be trash, right?
Then, I tested the giant against minotaurs GW. The minotaurs are AL, so a giant is a good matchup for them. Again, the result was not the one expected, the giant won clearly, even if the margin was not great. (The minotaurs had nearly no HP when they fled, I placed a lord near them for leadership, the loss is not due to leadership).
Then, I tested the minotaurs GW against the same hammerers that beat the giant. The minotaurs wrecked the hammerers.
The giant was supposed to beat the hammerers, it lost.
The minotaurs GW were supposed to beat the giant, they lost
The minotaurs GW performed very very very well against the hammerers, with there BvL ineffective, when the giant struggled against the hammerers (and it is not the giant which is trash, as they beat the minotaurs).
What I can see is that unit size matters a lot in a matchup. Armor-no armor, large-small-BvI-BvL and cost are not enough to deduce which unit beat an other in a matchup.
The giant struggled against the hammerers because it could not use all of his damages due to the hammerers small health per entity and performed well against the minotaurs because each strike could make more damages. Not all hammers could hit the giant but the dps loss hit harder the giant than the hammerers
The minotaurs struggled against the giant because not all of them could hit the giant but all the minotaurs could hit the hammerers. There, the dps gain (more hammerers could hit back the minotaurs) was more profitable to the minotaurs
In your experience, what unit size is more effective against an other? It is more complicated thran the more number the better or the fewer number the better.
Single entity seems to be better against monstruous infantery, monstruous infantery against infantery, and numerous units against single entitys, did you notice the same thing?
What performs better against cavalry or monstruous cavalry? For each unit size (infantery:120 , cavalry, monstruous cavalry, monstruous infantery, single entities), which unit size is the hard counter?
In each matchup, what will matters is the % of its damage output than each unit will be able to deliver, but it is not easy to predict to which unit it will benefit.
This coul be particurarly helpful for example with tomb kings, as they have 4 AL units in there roster (spearmen not included), all with different unit size.
NB: I do not feel the mass played a huge role in the tests, maybe il helped the minotaurs GW a little against the hammerers but the marging was really huge.
