Rito Doesn't Care about your toxicity, heres why......
Pretty simple actually, lets compare other MOBA's and league, and you will find one fundamental flaw that corrupts league and ruins it for players making for an awful atmosphere:
Dota2: during events get a reward for playing a game, win or lose you have a chance of getting something cool
Heroes of the storm: dailies stack for up to 3 days, all but one daily are based on playing games not winning
League: daily wins, events based solely on " win 2 bilgewater matches then win 6 more" so at minimum you have to spend 6 hours at least assuming you win every game........
Daily wins, not daily quests, winning for events, all of this puts pressure on players who like to earn the rewards and feel like they participated to WIN every game..... This pressure to win makes losing frustrating, especially if you are the only one doing well, which leads to the toxicity, and lashing out at teammates....... " But Fish its just our community is bad not the system, they need to make money"....... Absolute utter lies and trash, everyone here has probably at least PLAYED world of warcraft at least once, blizzard has a massive community and a large number of absolutely horrid members of the digital society whose only goal is to bother/annoy/distract/ruin other players experience...... yet Heroes of the Storm has a better community and less toxicity problems than League..... " but if they make dailies more reasonable and event quests reasonable people won't give them the monies", except no, IP cannot buy skins, and people spend handfuls of dollars to buy skins all the time, heroes of the storm does very well even with making dailies easier to obtain and less frustrating
TL:DR Leagues focus on only rewarding wins and not players simply playing and having fun with new game types or events or just dailies in general promotes the toxicity, Rito is making the problem worse not better. If Rito wants to make the community better? Put less pressure on the players to win all the time so they can just enjoy the game and play, without having to worry about being able to get that schweet icon or ward skin or whatever.
DISCLAIMER: THIS DOES NOT MEAN I PROMOTE TAKING AWAY RANKED REWARDS, RANKED mode is serious and should be focused on wins, I completely agree with the higher you get the higher reward you deserve, but for fun game modes like the current event? putting pressure on the players to win discourages the fun not encourages it
