Why should 2H/Polearms be different in M2:TW ?

[Shahed]

Hi All !

This is not a history discussion, it is a game discussion.

In MTW/VI 2.01 (or whatever the last version was):

1. Polearms such as JHI, Bills, CK, etc were offensive anti-cavalry units. They did their job VERY well and could be relied upon to do so.
2. Spears were a defensive unit which could perform very well against cavalry and hold their own for a short period of time against comparable infantry.

In M2:TW (PureFixer 1.13 and presumably official 1.20):

1. Polearms are now anti S&S (Sword & Shield). They perform very well against elite S&S infantry.
2. They are utterly destroyed by cavalry.
3. They do well against infantry as well.

My questions to you and to CA:

1. Why this change from anti-cav to anti-S&S/anti-inf ?
2. What has filled the gap, created by this change, for an offensive anti-cav unit ?

Salute !
