General and Spread.

I've playing atWar for about 2 years (with any interruptions). Nowdays I'm playing a lot and bought lifetime premium. Because of it, I've 2 following questions:

1) How to use my general? In wich armies should I use him? Where, how and why? What are the best improvements for him? How to use them?

2) How much should I spread my army? In wich ocasions should I create and use a big stack, and when I should not?

Sorry for too much questions. Nvm, I apreciate all answers

1)a. + b. +c.Put him in a battle you want to get better rolls,have better defense and better attack(obviously with a stack following) or put him in a stack with which you want to protect a city.General to be useful and effective though needs upgrades.
d. + e.Best upgrades for general would be ''General: Defence'' ''General: Ground Secondary Defence'' ''General: Ground Main Defence'' ''Faster General'' and ''Lucky General''.Each one of them makes your gen stack have better deffense,better attack,better rolls and more like that.

2)a.It depends on the game and strategy you play,if your enemy has big troops near you then play closely and carefully,if he is opened do the same but try to take the advantage and steal some of the countries he can't easily protect.
b.Use a big stack when you want to rush or defend something way too much,like game changing defend/rush.Otherwise I wouldn't suggest you to make a big stack since it can easily be tbed or killed.(Tip:Prefer to walling your stack in random places so enemy can't attack it)

I hope I helped,if any question inform me.
