a lvl 6 kat could stop this push with a fort by herself almost.

Put the mortal strike up and then whirlwind, that'd push em back pretty hard. If she had the slow-on-spell staff she could even get a kill or two by shunpoing weak heroes.

Alistar
Soraka
Sivir
Taric
Blitzcrank

Though you know your opps will get these 5 Champions,it really doesn't matter...

1.AoE skills all deal magical damage,and Champions can't deal AoE physical damage without Tiamat(except Jax & Malphite) .
So,if the team get many Magic Resist iteams,AoE skills become no effect...

2.Can your physical DPS teammate get enough iteams when this team begin to push(about 6~7level)?And,Taric's aura sucks!

3.Healers in LoL are all IMBAAAAAAAAAAAAA!!!!!!!!!!!!

promote rally is almost impossible to stop without a fort picked during champ select. given that blind pick makes it impossible to see it coming, the tactic can't be stopped by a 5-man solo queue if they don't know what they're in for. that said, picking fort as one of your champ abilities isn't really something a solo queuer would want to do, given that you only really see promote rally premade nubs once in a blue moon.

1 or 2 well-timed forts can kill a promote-rally rush. if they decide to drop all their promotes on one push, a single fort will burn through their supers leaving their team stacked in a lane underleveled and unfarmed for the rest of the game.

Its a Blind Pick issue... not a combat or hero issue. This plan is far too good right now in premades.

Need one intitiator-Singed (toss), Blitzcrank (Pull), Allister (Stun & Headbutt) or even Tristana with her jump+ulty. they come to you get one into your tower range, smash him, repeat. Didn't try it but it might work.

You know, half these problems are with people using synergistic ultimates, I mean the promote armor aura isn't the thing that's messing you up here is it.
