Q Buffs And Melee Minion Breakpoints
IMO the biggest possibility coming from these buffs is the ability to one shot melee minions with a fully charged W+Q so i did some math to figure out if this is possible or not. We're gonna be assuming you're level 9 with full botrk and dblade for these calculations.
Melee minions gain an "upgrade" at 30s when they first spawn and every 90s after giving them hp and ar. The usual game time when you're hitting the spike mentioned above is about 10 minutes which would put the minions at the 9:30 upgrade 7 and about to hit the 11:00 upgrade 8. This would give every melee minion 675hp and .1ar and 710hp and .2ar respectively. The armor values are negligible so I will just be assuming no armor for these calculations.
The newly buffed Q and the 55ad you have from items and runes plus the 89 base ad you'd have a total of 144ad allowing the Q to do 338dmg to minions. A fully charged W deals 233dmg bringing you to a total of 571dmg and adding in the 9% current hp dmg from botrk gives you an extra 40dmg bringing you up to 611dmg on a melee minion. So without fully stacked passive we still can't one shot melee minions, even once you add on the 45dmg from fully stacked passive you're at 656dmg which leaves us about 19dmg short of being able to one shot melee minions. If you take JoT trades and have the 5 extra AD your your Q does 342dmg, W does 239dmg, botrk does 39dmg and your passive does 46dmg still leaving us at 666dmg which is still 9dmg short of what we would need.
Now there is some cooking that can be done with runes like taking double adaptive which would let you hit that 675dmg mark, I haven't done the math but i'd assume kraken second would easily let you one shot melees but this is what I was able to figure out.
tl:dr with JoT and double adaptive you can one shot melee minions at fully stacked passive but idk if worth
