Very good analytic Video, I think we can all agree that this matchup needs some improovement.
Concerning the wildmen I agree with Fella: yes, you can quickly double their damage with the torches, however they are such a vulnerable unit, that this can fire back pretty quickly. At least in this matchup the scouts and their great synergy with the wargs is more troubeling.
Increasing the general damage of Pikes vs. Cavalry would already be a huge deal, not only in this matchup, but in countless other cases.
Cavalry is extremely strong in this patch, which leads to straightup cavalry battles in almost every game, because you cannot counter it with adequately with pikes. The player with the cavalry advantage has already won the game in 90% of the matches.
(it is almost impossible to counter a fast, harassing force, which can fight even pikes headon, while also having to deal with an infantry army, without cavalry). But that is maybe a point for another balance video.
The other suggestions are also very reasonable, lets see if something can be improoved in this direction.
