There is an Issue with Gold Income
Not just that you can earn so much more gold so much quicker than you used to be able to, but klepti and support items. Look at LCS with the TSM vs C9 and 100T vs CG. Both games showcase how Klepto is insanely strong and 100T vs CG showed how strong support items gold income is.
Example: C9 was down 800 gold from tower plates, first tower to no towers, 1 kill, and was losing in CS in every role at 20 minutes yet was only down 300-400 gold. Like how is that ok?
