I don't have AFKs often.
If they're not buying items, they may be doing the Stat Anvil strat. If you don't buy any full items (you can still keep the one Mythic one it gives you automatically) and only buy Stat Anvils, you become eligible for the "Stat Anvil Shareholder" option to randomly come up. It's a flat % increase on all stats from Stat Anvils.
Basically you can do that on any champ that doesn't care about items and just wants to stat check. Lots of fighters go for it.
