I played an ATAM (All tank all mid)on summoner's rift. We all took the same spells tele-revive, and we all built the exact same tank items in the exact same order. Sunfire, FoN, thornmail, etc. The other team (which did not know we were playing ATAM) had too many squishies so they got all the way to our inhib turret early game before they couldn't kill us anymore cause we too tanky. We crushed them late game and won. They killed us like 80 times and we killed them like 20. Oh and we were all in: everytime we came to lane we tried to get kills even if it meant turret diving. (Hence the tele revive combo.) I played shen and we had a garen, rammus, pantheon, and alistar. Good times.
