Friendly Suggestion To Air Dragon
Before I begin, I'd like to point out that each dragon is good in its own aspect.
Fire Dragon - General Skirmish/Teamfight Augment Earth Dragon - Pushing Augment Water Dragon - Sustain Augment Cloud Dragon - Split Pushing Augment
This is a cool mechanic to explore, and I think it could be nudged in the right direction with a slight modification.
Current: Grants bonus 15/30/45 additional movement speed while out of combat.
Suggested Change: While out of combat, gain 20/35/50 additional movement speed.
NEW: Every 1500/1400/1300 units traveled while out of combat will grant a stack of "Allied Winds," up to 10 stacks. Upon entering combat, the first basic attack or spell on an enemy, will slow them by 30% for 2 seconds, decaying rapidly after 0.5 seconds. Additional damage will discharge a stack each, dealing an additional 30/35/40 magic damage.
The flat movement speed buff will add to its basic power, while the passive helps with split pushing. Normally when split pushing, there are one or two enemies defending the tower. The slow and damage helps to duel them, and if no enemies are around, it helps to whittle down the tower.
The damage may seem like a lot if you take into account 10 stacks, but that's the distance from your mid inhibitor tower to the enemy's mid inhibitor tower. The stacks are discharged one at a time so you can't roam around doing nothing and then discharge them on a tower for 400-600ish damage and repeat.
