This is happening since years, and yet nothing has been done... Its not the 1st post that talk about this! When u are lower than 30 and is matched against lvl30, just report them, maybe Riot will do something!
However the real solutions are so easy, too easy and obvious i guess... :
DO NOT ALLOW LV30 TO PLAY AGAINST OR WITH PLAYERS LOWER THAN 30!
AND, BRONZE/SILVER/GOLD PLAYERS SHOULD NOT PLAY AGAINST DIAMOND/MASTER/CHALLENGER ( this rules is applied for ranked but not the other games mode... then everyone ask why is there toxic players???
- the lvl30 are more experimented than the lvl 10-29, then its a free win for the team with a lv30
- the team without lvl30 will ALWAYS LOSE with HUGE amount of deaths, **how the losing team can't be toxic after such humiliation ? lol. Just check that sreenshot and the item build... THEY DONT WANT TO PLAY AGAINST LVL30 WHEN THEY ARE LV20 **
- the battle is unbalanced BEFORE IT START (runes & masteries are better at lv30)
- 2 bronze, 1 silver and 2 gold, how are they suppose to win against 1 bronze, 2 silvers and 2 diamonds? Everytime i see those matchup, the team with the diamonds+ wins
Until they apply the solutions, just report all the lvl30 if u catch 1 in the enemy team and you are lower than 30.
And if you are lvl 30 and your team (with player between bronze and gold) play against a team with a diamond, master or challenger, report this diamond/master/challenger.
Why report them? because its a form of harassment!
