Well, I'm going to be using solid blocks of pikes and charging into melee as soon as possible in ETW, just as I used to in RTW and M2TW. It doesn't matter if my pikemen become obselete, they will still fight like men.

Come what may, most of my battles will be locked down in melee. I refuse to change my tactics.

(will archers have a greater range and overall superiority over musketeers, I wonder?)
