Double q is not fun during the early game to mid game for viegar I believe it needs a buff

When playing viegar this is usually the case to utilize the double Q: You have minion 1 and behind minion 1 is minion 2 -Minion 1 is being attacked by ur ally minions and its health is being lowered -You want to use your double q -You would have to auto attack minion 2 as fast as you can so that it can have a lower health that you can kill with your Q -Then you have to aim your Q perfectly and if minion 2 move you have to change viegar position (Oh yea the annoying part is when minion 2 who was behind minion 1 decided to move beside minion 1 omg you just wanted to scream at that moment)
-If you aim properly you are able to hit both minions and kill them both. But, if you calculated wrong minion 1 would be dead but not minion 2 whose health is literally like 10 hp. Now you have to auto attack it fast (Or else you loose the gold) before your ally minions kill it because their priority shift from minion 1 to minion 2. -You have to think like this while also guarding and dodging from mobile or pokey enemy mid lanner

The benefit of double Q only comes when you can finally kill 2 minion (at full health) in one Q shot shot. This can only happen during mid game and having a rabbadon deathcap as your first or second item. I notice that you would be continuing to do the auto attack of minion 2 until you get rabbadon deathcap.

The buff I believe that should happen: On Q the second ball that come after the first ball should have its damage amplify by 10 to 50% (Any number you feel it will be balance) on enemy minion. Which means the q that hits minion 2 will have its damage amplify by a percentage. Of course this damage amplify does not affect enemy champion. This buff will make it easier on viegar during the early game as the health of minion 2 is always going to be higher than minion 1.
