Suggestions to improve the new rune system

I think there are quite a few runes that either need slight nerfs or slight buffs.

My recommendations:

Press the attack should be dropped to 10% from 12%. Manaflow band 60s CD to 45s. Celerity 8% damage from bonus MS to 6%. Gathering storm: 10 minutes intervals to 8 minute intervals Legend Bloodline: .8% per kill up to 8% to 1% per kill up to 8%. Absolute Focus: 70% or above requirement to 60% or above. Scorch: 30-90 damage instead of the current 30-60. Guardian: 75-175 shield instead of 60-150 Font of life: 5+1% max hp over 2s to 5+2% max hp over 2s Overgrowth: Every 8 minions or jungle creep to every 7 Arcane comet: 30-100->45-115 Aery: 30-80->40-90 shield
