I had the same problem the other day while playing Alistar, built censer (awesome item on him) and Banner of Command (teamwide MR, and I wanted to be able to help counter the enemy team's pushing), one of my teammates was like "Ali your build is trash, wtf? Not tanky..." despite us having a volibear and a chogath both building tanky... -.-;
Luckily the enemy AP nidalee shortly thereafter gave me some retribution when she said in allchat "WTF IMMORTAL SEIGE MINION" after she spent a solid minute trying to kill it (spell immunity bwahahaha!).
Interestingly, the AS buff from censer plus the pushing power from my buffed minions helped significantly when it came to winning the game, because with my heal it allowed us to make extremely fast, extremely hard pushes any time we managed to ace the enemy, even if I was the only survivor.
Baron buff, Censer, Banner, and Elixer of Ruin just made for silly-strong minions, btw.
