The game has become pay to win ever since BE came.
So ever since BE came out the rate of people getting new champions are so low compare to people who already have them save up. It was obvious Riot did this on purpose to make people buy RP if they want to be up to date with over loaded champion kits, now basic champions rarely are a match with the new champions and all their 2nd "active/effect" ability.
Yes this is free to play but it has clearly become a pay to win situation.
People can say that this is free to play and you can still earn BE so stop "Whining".I wonder if you ever played a Nexon game like Combat Arm, they did the exact same thing where 1 game gives little to non gold while buying a guns take over 10 hours of play to even rent out a gun for 1 day. Tell you the truth Combat Arm is even faster at making gold to buy guns then league right now which is funny as F**K when it's Nexon.
