Does anyone play end-game material with maxed-out 3*s? If yes, which ones?

What the title says. Are there (very) skilled guys (or girls) in here that can pull that with maxed-out 3*s and, if yes, which ones...? I am talking about (at least) ACT 4 , RoL, LoL etc.
It would be good to know if you can count on certain champs to take you to the top and that would be worth maxing out, instead of some not-so-useful 4* champs.
Thanks!

I used my maxed 3* GR for a couple fights in act 5.4 as i used him as synergy for Blade, but they were generally easy no fuss fights that ended up being around 5min long and in the 250 hit range.
With accessibility of 4* i dont think its necessary to worry about 3* too much except for clearing act 4 amd heroic/master in the EQ.
Man, you are clearly a much better player than I am! I have only completed (not yet fully explored) Act 4.1 and I use a couple of 5* and 3 4* on my teams, with the occasional help of few spare health potions.I see that a Colossus is at a gate down the road, I only have him as a 3* and I already worry...
