Can you play Hotseat (PvP taking turns locally on the same machine)?

Bought the game to play with friends, but the online button is missing. Any fixes to this?

Would be really nice if you had an option to set rally on the villages, this way we can expend less time setting orders on every unit, would be really helpful to reduce time on big multiplayer games.

How do we create mage towers?

Would be nice when you give unit this order that the unit/map would actually show it. Maybe have the Soldier or Builder go to his knee? Something similar? Or use Shield icon, like the arrow is used for movement?
