Gaming Laptop under 1500 mainly for league of legends?

I'm looking for a gaming laptop under 1500.

I mainly play League of Legends, watch a lot of movies and use Microsoft for school.

Knowing any laptop even under 1000 can play lol, I want to make sure that I don't have to play lol at lowest settings. I have Lenovo y50 for almost 2 years and it is a good laptop, but when playing Lol, I have to set at the lowest settings in order to get decent fps.

I do not wish to buy another Lenovo, rather I was looking into MSI gaming laptops.
They have a lot of series and models and I have no idea which one is the right one for me.
Was thinking on Acer Predator Helios 300 but did not like the WASD highlight, but prefer backlit keyboard.

One of the major reasons that I bought Y50 was because it looked amazing.
I do care about how cool it looks. Prefer 15.6, and want to avoid thick laptops since I got used to the Y50.

Also, something which has fewer issues with heat, which can withstand a moderate amount of work or multitasking without overheating.

And of course, a rig that can play League maybe not on max settings but at least on medium settings with no fps drop or lag, for a long period of time(sometimes I play LoL for around 6 to 9 hours continuously).

Battery life would not matter to me much since I never found myself using it without connecting the charger.

Thanks in advance, any suggestion would be great!

First, if you're going to get a real gaming laptop, it's going to be thick. Absolutely no way around that. The Y50 was barely a gaming laptop. It's best video card was outdated before it even released.

$1500 will get you a decent alienware 15 that will allow for ultra settings in LoL. It comes with a GTX 1060 OC.
