I was stomping so hard as 5 ring fizz + lich bane in an aram
When I got bored of that I just sold the rings for a deathcap
Actually, yes, that might be actually somewhat effective, but if you don't upgrade them when proceeding to late game, you might actually lose because the team because a Lux having a Rylai's Crystal Scepter, giving him/her over 500 HP and 80 with only wasting one slot, while 5 Doran's rings waste 5 slots granting only 300 HP and 75 AP, with a big amount of mana regen easily gotten by buying a athene's grail,thus making you waste a whole of 3-4 slots when you could just buy rylais and athene.
