So, with the current metagame, it seems that competitive teams will be using 5 tanks/Tank hybrids with a combination of Rally/Promote, and Heal to compete. It seems with the current heroes that the best combination for accomplishing this is Amumu, Nunu, Taric, Allistar, and Morgana.

What do you think can be done to compete with this combo?

Well, atm with blind pick it will prob be hard to counterpick at all, but in the case where you know that the other team will go for pushes, I gues a team with 5 smites and some people rushing for Madred's Razor might be able to counter it?

And yes, Fortification also helps out.

The game is over in 15 minutes if you don't counter witht he same strategy, or stack fortification.
