Playing AD Malzhar now is the worst choice one could make in champ select
Before the update, Malz could have 3 voidlings up constantly if he was spamming spells. They each had a 1.0 AD ratio. The first would have 100% bonus attack speed, and the first and second would have 50% bonus attack damage. That's (1)+(1x1.5)+(1x1.5x2)=5.5 AD. Now the best you can do is 0.4x1.5=0.6 per voidling. Supposing you can get out 5 voidlings, that's a total of 3 AD.
My math may be wrong; I don't recall what the old voidling base damage was (or if they had any). But either way, it (or total -> bonus AD) doesn't leave the new voidlings in a stronger state.
A 50% reduction to AD Malz's damage is not what I'd call "Keeping the AD build as an option", especially when the AD build was marginal to begin with. Can we get some kind of buff to correct this?
