And I'm telling you that it doesn't matter if they do or don't. It drops coins like candy. Body blocking one 25 or 40 gold coin doesn't stop them from getting a ton off of future waves, kills, and/or assists in the near future.
It works for pro play because supports are expected to roam a lot. It doesn't work in solo queue because SQ supports don't roam even close to that amount. That's why this toxic solo queue environment currently persists, and why enchanters are actually pretty shit in pro play despite Ardent being balanced as intended (used as a strong build foundation on some champs, but not required on every champ).
