Ya, i made a long post about this for 0.952 but I guess the devs just dont realize how OP it is. 

Mounts with +2 move upsets balance on so many levels:

1) Exp is gained much faster because you can fight more often.

2) You can do easy attacks on cities since there is no way your opponent will get back to defend it in time. 

3) You rob your opponents of the opportunity to gain exp because you get to the monsters faster.

4) Tactical fights are easier because you get the first hit. 

5) You clear out goody huts before anyone else even see them.

6) Tactical fights are easier because you can kite.

7) You explore the map faster to find good spots for cities/outposts.

Read my original post about OP mounts here. 

I think it would be cool, if unfeasible, if instead of being prone immune mounted units could be knocked off their mounts for the rest of the tactical battle. That would be very cool and and lead to interesting situations.

A mount should give ts rider absolutely NO bonuses (except maybe the ability to get his head stepped on) unless they have the traits to utilize the mount.  Then, then mount can be a powerful tool to a hero or unit specialized in mounted warfare.

I have to agree.

The ironic thing is that Wargs have been increased to 150gildar when they weren't even worth 80gildar.

I'm fine with horses being worth 120gilar. I won't be so extreme as to sell all my gear to get one.

However, Wargs need to be worth that 150gildar and I think the best way for that to happen is to add a +3 attack to the creatures. This way, the player will be torn in getting a horse upfront, or waiting for the warg. And even some types of champ will work better with a horse and others better with a warg. Both will still be overpowered, but at least their relative power will be in check. Then it's just a matter of getting the price right.

I don't really know why horses give +2 movement anyway. It is a well known fact that a man can outrun a horse for a few hundred yards. The tactical battles are not played out in an arena where having endurance is important.

Horses should be re-imagined to do stuff like

1) trample enemies without shields or spears. Trample means +50% damage

2) Allow the unit to ignore movement restrictions caused by proximity to other units

3) special abilities like "charge" where the enemy is not allowed to counter-attack unless they are also mounted

Wargs could provide an extra cutting attack bonus in addition to some sweet dodge. They could also give a bit of bonus when fighting against beasts.

Both types should also have some sort of weakness, such as being scared of fire or dealing less damage against spear units.

That is the current problem with the horses. Horses do not have a drawback. Why would you choose not to ride a horse?

First things should be known is that entering caves or buildings should not have horses (wargs maybe).  Thus, if there was an indoor tag that says hey you can't complete this quest mounted (or on a horse).

I don't think that mounted units should do less damage to spear units, but should always take damage when attacking a spear unit (a thorn type effect of pushing past the spear).

Maybe add the extra ouch of if you take so much damage in a combat the horse or warg dies. Like over 75% or something. That way you would have to purchase the mount over and over again.

Wargs are always cooler than Horses. I dont care about the stats
