The Problem Isn't a Lack of Communication. It's that Support is Genuinely Unfun to Play Right Now
Support experience has been at an all time low since the change to experience masteries back in season 5. Riot keeps introducing ways to help supports catch up, but these are usually based on kill experience. The ward XP change was...okay, I guess? Kill experience, on the other hand, is completely useless for the support who is behind. Your team is not getting kills and you are not getting assists when your lane is behind. Like the change that "if you don't get an assist, you can still get XP for a kill if your body is in range for 10 seconds after your death." Whoo, boy. That's what I want to hear. If I get murdered, at least my team getting a kill without me helping in any way will keep me from falling too far behind. Right, that's going to happen.
So it's no surprise that people are just leaving bot lane to try and get XP in the enemy jungle. I did it back in the preaseason. It's just honestly better for all five members of the team to have reasonable experience than it is for the ADC to have more gold. Particularly in the mid game, where most games are decided. Don't believe me? That's how this guy with the Nunu Master counterjungling support strat has a 53% win rate. He sets the enemy jungler behind, and himself ahead. And when team fights start, a tank with experience and a bit of gold is more useful than an ADC with one lethality or crit item.
This isn't support players breaking the meta. This is support players adapting to the meta. ADCs have been feeling weaker, games are decided earlier where ADCs are less relevant (ignoring the recent rise of lethality because that was Riot's response to try and fix this problem), and supports have less XP. Combine that with the fact that many traditional supports have terribly low base stats already, and being down three levels can put you as much as 200 or 300 health and 20 armor below the rest of the team. Experience is wildly important!
Riot, just stop trying to conserve this meta. It's not going to work. Revert lethality, and let ADCs just die off as a class. Then we can have a jungler and a counterjungler, and three solo lanes. That will actually make jungling less PVE! It breeds, wait for it, MORE PLAYER INTERACTION! Just like you keep claiming to want!
comming in for their squishy then they'd be worth to play but now?? eather tank supp or malza supp to counter those Trains.
