I find I keep changing my mind on the value of Knights in general.
WHs give you a well balanced range of units. Yay! No need to build a stable.
NH units are missing an anti-LI (skirms) counter.
On the other hand, JP and EK are very pop efficent. And, you can get the +15% hp/dam upgrade for knights.
These days, I tend to lean in the direction of building just WH units (BBs aside). However, I do build AK - 1 NH is normally enough. In theory, Coyotes can handle cav, but, in practice I find AKs do a better job.
Anyway, if like me, you lean toward WH units, you can ditch Knight upgrade cards for something more useful. Is the Ruthlessnes card worth it?
Any thoughts?
