whats the quickest way to earn ip?

There are a few tips on gaining alot of IP "faster" :

1. Buy IP boosts(Not per win, or if you got enough money, take a free day, Per win boosts + 1 day boost as they stack and grind a whole day i guess :P ).
2. Make the matches longer, longer match = more ip, shorter match = less ip
3. If there is an internet caffee/place with PC's(however you'd like to call them), gather a few friends and play with them, When you're having fun time goes really fast and you'll end up having lots of fun + getting lots of IP too. (When you're having fun you will completly forgot about farming IP and the time, its a win win).
4. Get the First Win of the Day bonus, its 150 IP and if you complete it daily, each week the bonus accumulates in a total of 1050IP(bonus ALONE).

Play with friends, spam arams.

forget about IP for a few weeks and just play for fun

buy IP boosts and prepare for a very very long grind
