My turning point was when i was planning to buy the reborn skin for alicia until I saw the scummy tactic they threw at players to make them buy MP twice to get it, because that's the most popular skin for her.  It costs 1250 MP and they only sell a pack of 550, 1200 and 2500 MP at the store.
When i saw that i said fck that i rather play with her original skin

 i wouldn't spend more than $5 for a skin. I would feel like an idiot spending more than that for an aestethic item.
 And for the people saying we have to support the developers and all that bullshit give me a break, I would say a good amount of people who play this aren't swimming in cash and got priorities in real life.
And the people saying but theres tickets that let you earn mercury points.
Unless you have a dedicated group of people following you blindly, It's almost unreal to get one of those disgusting overpriced skins, And it's even harder when this game doesn't allow EU and US people play together (It baffles me that this is even possible in 2018)
