funny thing ever since duo bot lane has been meta (carry + support) it has been a gold funnel strategy for the carry to get all gold/kills and the support get gold via gold income item + passive gold so that carry can hit their power spike and items sooner to take over and carry the game.
now that people use it in a different way Smite mid and a support with a gold income item splitting jungle exp and giving jungle gold to mid with smite its an issue and the sky is falling.
now i have seen it work and fail in PRO PLAY there are ways to beat it and counter it. i have yet to see it be effective in solo queue but thats me.
it seems like a strategy that premades/teamspeak coordinated players can pull of if they do it right and typical solo queue teams cant.
