AOE Team Stat Diffing Strat:
Frozen Heart: Cripples the attack speed of enemy champions within 700 units by 20%.
Bandlepipes: Slowing or Immobilizing an enemy champion empowers you with Fanfare for (Melee 8 / Ranged 4) seconds, granting you 20 bonus movement speed. While empowered, you and nearby allied champions also gain (Melee 30 / Ranged 20)% bonus attack speed.
Frozen heart slows enemies' in range attack speed by 20%, bandlepipes gives movespeed to user, and 20-30% attack speed to allies, creating a team difference of 40-50% attack speed.
Add in these two for even more stat differential:
Rylai's Crystal Scepter: ability hits slows enemy by 30% movement speed. The slow makes procing bandlepipes easy on every ability hit.
Shurelya's Battlesong: gives 30% bonus movement speed to team, stacks with bandlepipes speed on self. Makes a movespeed gradient of 60% across teams, even more for bandlepipes user.
Optimally, you create a difference of ~50+% in both move speed and attack speed for your team realtive to theirs with good uptime.
