ip per win boosts vs skin boosts.
besides the gifted win boots that we occasionally get, buying them in the store is not very profitable.
with the largest boost amount (since it gets cheaper per if you buy more), a 50 win boost, it costs 2560rp. they give a MAX of 168 ip if you play a long lasting ranked 5s game. those 50 wins give you (at max)50x168=8400 ip.
now lets go to aram. buy a skin boost. 95rp per boost, 200ip. lets use that same price as the 50 win boost. 2560/95=26.9. lets just say 26. 26x200=5200.
yes you do get less ip for the same price, but EVERYONE gets it. so in reality the 26 skin boosts gives 26,000 ip. the calculations are for the 50 win boost. the skin boost is even more profitable if you wanted to buy a smaller pack.
if you and 4 buddies just keep taking turns buying skin boosts, it gives a TON of ip very fast. plus it is much faster since you get it everygame, rather than just a win, as well as aram matches being much faster than ranked 5s matches. if you dont want to be selfish, or have a group of people that want to grind ip for runes, please buy skin boosts.
