Supports counterjungling was top tier Meta on more than one occasion
I specifically remember The most common thing being the Jungler giving their Nautilus support lvl 2 off a camp so they could tilt the enemy Jungler while the Adc solo laned for the first few minutes. (in fact it was so meta I was once given the first camp from my Jungler just because I was Nautilus Supp, and this was in bronze)
That was just the most common scenario, Supports harassing enemy Jungler lvl 1-2 has been a thing for as long as I can remember.
And do we really forget the "smite meta" so easily? When top took smite for hulk, mid took smite for Runeglaive, and even some Adc's took smite for Devourer, I don't recall this being considered bannable.
The truth is there is a double standard for supports when it comes to breaking the meta because Rito constantly balances(and from what we've recently learned, enforces) the game around one role babbysitting another for 20 min straight, which contractions their goals of diverse gameplay(Thor forbid someone shows a playstyle that gives the Supp role more appeal).
Seems everyone on the Rito team is too afraid to comment on this topic though, unfortunately..
