this is truly killing Leitis LOLThere are many approaches you could take, and they all could work.
My basic idea would be something like that :
HP : 85, 100
Attack : 12, 14
Armor : 1/1
Cost : 60f 50g
Train time : 11s, 9s
But I don't think I have the perfect answer ready, this is one option I think is worth exploring, but there could be other interesting opportunities.
who wants a horse version Shotel....
I think most people would prefer building 6 stables over 2 castles for similar production, in this case.
Basically Knight line is better in open map and vs archers
Leitis is better in melee fights, durability and upgrade time
You haven't talked abt upgrade time at all. Upgrade to Paladin totally need >4 mins
Upgrading to e. Leitis just <1 min.
Assume u reached Imperial 2 mins slower than normal due to the need to build 2-3 castles for Leitis production.
You are still >1 min faster to reach E. Leitis than Paladin.
