My arc 57352 The All-Seeing Eye auto SKs to 45 and is solo or team friendly. It uses stock mobs (Crey, Council, Arachnos, Nemesis, Rikti, and KoA) and is doable by virtually any build with SOs.

Governments have fallen to the power of social media. Gaming companies can too.
"The Amulet of J'gara" (1709, Heroic) runs from level 25 to 33 and the customs don't appear until halfway through. None of them are mezz-resistant aside from the AV and even then I give you plenty of optional backup.
"MacGuffin Delivery Service" (1567, Villainous) runs from 35 to 40 and is all stock enemies. Anyone should be able to solo it.
"The Portal Bandits" (3326, Heroic) runs from 40 to 54 and is designed to be tougher than normal. Predominately custom mobs which pack a lot of buffs, debuffs, and some mezz effects but lack mezz protection of their own. They're designed to keep you on your toes and a team should have fun with them.
All of my current published arcs are playable 1-50, and none contain auto-SK features.
"World's Great Philosophers" is the one that's been most changed for i15, because the custom group there is a mixture of standard issue mobs, who now have all been renamed or recolored, with custom mobs. Being a mixture, the standard mobs will only spawn if they are right for your level range.

Try my three in the Tubbius Trilogy (as it's been christened!) in my signature! Controllers are my main toons, and these arcs are largely playable by any level, with a possible exception of PENGUIN; the first two missions of it are minimum level 30.
City of Ho Ho Ho: 5-20 on all.
PENGUIN: 30-54, 1-54 on final.
This Costume Contest Sponsored By Tubbius: 1-54 on all.
Check 'em out. 
You can find any of 'em by searching up the name Tubbius.
Edit to add: These three arcs are meant to be sequential. Try 'em in order, and let me know what you think!

In the sig, my 4th of July arc auto levels to 40 making it fine for most groups with their core powers and I don't think there are too many mezzers in there.
I am looking for some arcs to do while leveling up a few new toons. Basically what I am looking at is getting something that has a minimum level of 15 and goes up from there. I know with issue 15 many authors are now setting a minimum mission level so that it always auto sks. Part of the biggest issue with the AE is the non-sking some missions do but since this is taken care of to a point in issue 15 I can start doing arcs with big groups and not have to worry about reforming. In addition to the level requirement can you recommend some that are missions which are friendly to control ATs? I have been recruiting doms for this, I want to make sure they dont get left out because controls dont work on some custom critters.
