Yes, i would like to see how using pikes offensively would work out in this game.
Also, i have a suggestion to the devs. I suggest incorporating Rifles, known as 'studsare' into the Swedish army as a weapon for officers.
A studsare is a short barreled rifle, the word derives from German ' stutzen ' which developed into schutzen. This arm was used by sharp shooters and was commonly associated as a officer weapon. I read about it today in Peter Englund's ' Poltava ' where he mentions both sides having these sharpshooter but does not go into any detail of the Russians, only mentioning they have sharpshooters.
Even if if you don't want to have it in the officer class i am sure you can find a way to incorporate it
