First of all, it doesn't do anything to yourself, meaning that while everyone is slowed and stunned you can move about freely. Second of all, you will notice that it slows allies less than it slows enemies, meaning that allies will still have the upper hand in a teamfight. It's mostly all about who has the advantage, and with this ulti, you have the greatest advantage since you aren't hindered (and can basically spam right-click or "Wartime Measures" to possibly get a hero kill), and your allies have an advantage as well since they'll still move faster. The aim of this skill is to put you on top in terms of freedom of mobility. It can be used as an escape for you or you're allies or as an initiator for a teamfight, giving your team that extra advantage going in.

Again with the stun. it doesn't affect yourself, giving you one second to do as you wish with no one to say otherwise. As with the slow, you can spam right-click or "Wartime Measures." Another situation where this is useful is this; In the event that an enemy has really low health, use your ulti to stun everyone, and kill the enemy hero with no chance of a killsteal.

Good point, but I still think a speed boost for ur allies and a global stun for ur enemies would work just as well.

Brother please have some mercy, Q is a ravage without the damage with a mix of Global Silence on a mind boggling 600 radius area meaning you can stun an enemy from as far as 600 + 950 = 1550 range which IS ridiculous. Death to blinkers.

I definitely see your point. I made a post while you were typing, I think. Read the post above yours and get back to me on that.
