Bio-Arcane Barrage is Overloaded and Kog'maw's Itemization sucks

Can we give a good hard look at all the things this ability does?

• Range Modifier

• Attack Speed Steroid

• Doubles Maximum Attack Speed Cap

• Attack Damage Steroid

• % Max hp on-hit

That is a ton of shit compared to pre-work Bio-Arcane Barrage which only did two of the five listed above. The best candidate to be cut would be the percent max hp on-hit and increase the basic attack damage modifier each level you put into it 50%, 60%, 70% etc. This would compensate for the lost damage and allow Kog to better itemize Attack damage and Crit without harming current builds.
