Just my 2 cents;
First, wow what a job! Great Idea.
I don't like how the flags spawn. They always spawn almost 'right in the middle' of the two armies.
I'd say the army that advanced the most should have an edge, right now if you just spawn and you are lucky to stand on a hill... why even move?
SOLUTION
I'd say make it worth marching forward please! Put the flag close to those who traveled the most.
Some maps have hills larger then the kilamanjaro. Please get rid of them.
All guys are more or less good. BUT nordic scouts are worthlesss, sometimes it takes minutes before someone of your group finally accepts to be the fucked up nordic scout looser.
I'd like to give my idea to make it even more challenging, buff and nerf so this is more accentuated:
Archers good versus infantry (if infantry rushes into a rainbow of arows they should be hit HARD)
Cavalry good versus archers (nordic archers are too good against cav)
Infantry good versus cavalry
Sometimes I hate it when people spawn in your team, and they don't communicate, mostly dont even speak french, english, german or spanish (Yes I speak em all more or less).
They mostly just do their thing and charge which always makes you loose your multi.
But I don't want to be crying here all the time.
I'd say the commander who was there the longest or who played last game should be able to decide to allow new players or not.
SOLUTION:
I'd say add valour for people who kill more then 1.5 x their armysize to buffer for previous QQing. If you play smart it doesnt matter if your team really wins.
Right now I'd say, don't nerf the gold. Mostly you don't get further then X3 cos a noobie or non english speaker joins.
But with that valour I'd say add some upkeep again... !
I hope you'll implement some of this.
