Most overrated unit

[caravel]

Chivalric Knights and Gothic Knights. Just plain not worth it. You want your cavalry to break the enemy with their charge, not stand and fight it out and take losses. They're noice to have, but most of the time is just not necessary. you Royal Knights come freely with each new heir and are just as good or better despite their small unit size.

Gothic Knights I agree, it takes so long to tech up to them that you've usually finished the campaign before they become available anyway.

On Chivalric Knights though I disagree. Chivalric Knights on the other hand do take quite some teching up but are worth it, have a good charge and more importantly can be dismounted to Chivalric Foot Knights at any time - and when you have CFKs you don't need halbardiers.

I actually prefer Feudal Knights simply because they are easier to build and pack a similar punch on the charge.

Feudal Knights actually take far too much to tech up to. As a turtling player I usually find that when I can finally train feudal knights it's the high era and they're obsolete anyway.
