Which sounds to me like snowballing is currently OP.
In other words, what used to be small advantages are now big due to the snowball effect.
There are many variables which produce these chain reactions but the most common one so far is first turrets that usually come right after first blood, resulting in a ridiculous powerspike of gold, exp, and pressure across the entire map.
Most common scenario is 3-5 man gank bot lane turns in to first blood, first turret, then most likely first dragon.
Not sure who would agree but I personally feel the game's fucked right now.
