Epicnamebro's starting class challenge series videos.

ENB is running a series of boss challenges on Youtube and players are uploading their battles as video responses proving that they completed it. If anyone would like to see starting class characters with severe equipment restrictions as well as no healing allowed take on some bosses you should check it out. He's not doing them all as some are pretty easy, but he's got Gargoyles, Capra, Qualaag and just started O&S. Some of the O&S fights are pretty damn impressive given the restrictions. I'm doing the challenge with a Sorcerer but did a few of them with a Warrior as well.

I like the series, it shows a straight up way to take out the bosses the way it should be. If you can take out the bosses with your starting equipment, you should be able to do it with fully epic gear.
