Mejais on lux?

I am looking for your input on if you think mejais is good or bad on lux, and why. Here are some pros and cons I know of. Pro

1. stacks op, and eazy to get with luxs long range w,q,r,e all are very good for stacking
2. Alot of cheap dmg/late game cdr- lux ult spaming op!
3. When you go Mia the enemy panics, this is huge as it helps out your laners, even more so if you roamed once also lux lazer has a huge range which is not commonly warded.
4. 180 AP when stacked! you get 20 base from the item
5. when stacking over 10 you have a huge voice with the lead able to lead alot more

Revelent facts

1. Large focus on mejas player- if you can handle it your team has alot less to worry about. its even better if they over invest to kill you and lose a team-fight
2. For me some players think I can pull it off at my current elo but wont be able to at higher elo {these are plat players and above}
3. Mejais not a gold sink if you have over 5 stacks! simular to buying a big rod.

cons

1. Unstable AP death is a big deal 10 stacks = 80 ap
2. have to play more passive- sense I am naturally passive I dont mind this.
3. considered BM- honestly who cares if it is.
4. teamates will flame if you fail stack
5. massive drop in AP will make you feel weak.

Overall I feel its a viable item, but sense this item is so heated Id like to talk about it some more.
