The Commando Champion [ Concept ]

So I had the idea of a new commando style champ for the game. It would be a marksman and the the abilities would be as follows Passive- Squad Intel, gains bonus attack range based on the number of nearby teammates 1st ability a Dash that provides a short movement speed buff afterwards to re-position like Vayne's Tumble with Draven's Blood Rush

2nd Ability a grenade that explodes after a short delay like Corki's Phosphorus Bomb

3rd Ability the Ability to switch ammo types for a short time/ next few autos. The ammo types would be Incendiary which applies a short DoT on autos like red buff, Full Metal Jacket which gives Armor pen, and Explosive which causes autos to have a small aoe. Similar to Twisted Fate's Pick a Card but the ammo chosen would be random or the ability would just be one of the aforementioned ammo types.

Ultimate the Commando uses his training to gain the ability to temporarily be able to auto attack while moving although at a slight movement speed penalty.

Tell me what you think about this concept and feel free to post any ideas or suggestions you have below!
