One for All = tanks always win
Pretty much every game I'm facing tanks, eventually they just stop dying and we can't stop them from pushing our base. They can just stack items with only 1 resists and they get super tanky.

That's why one guy always does an off-meta build.

Thats funny, because in my
vs
match, we ended up losing. For some reason Malphite always has more damage output every time I fight one
Lol, nope.
I beat Darius as Soraka, and was beaten as Malphite by Yasuo. Taric got owned by Janna. Nunu also by Yasuo and Lux. Braum by Shaco. I'm just skimming through my match history here. About half of them counter your claim. The other half are tank vs. tank or squishy vs. squishy and don't relate.
So far my entire experience shows the outcome is dependent on two things:
a) The SPECIFIC champ matchup. Not types of champs. b) How much your teammates feel like derping out constantly, which so far, I've found they do more in this game mode than most. Shocker.
You must have just gotten some bad SPECIFIC champ-v-champ matchups. And were probably stuck with players who don't understand counterbuilding in this game mode (which is far different from any other game mode, and yet, doesn't govern 90% of players. Half of who would probably be perfectly willing to spam-rage meta strategy in regular queues, but will only put half a thought into what works in a new game mode, where no one has yet told them what to do. Psch.)
