Do any of the high level players actually have unbalanced mana masteries?

[Sirrian]

For any math-heads out there, we use a pretty common diminishing returns formula for Masteries & Mana Surge

SURGE CHANCE = MASTERY/(100+MASTERY) 

So:

• Mastery 0 = 0% chance
• Mastery 20 = 17% chance
• Mastery 50 = 33% chance
• Mastery 100 = 50% chance
• Mastery 200 = 67% chance
