Worst Army compisition to go up against?

For me, it's always WoC. Most of the players who bring WoC lists, bring the hardest lists they possibly can and tend to be WAAC players. So it's no fun for anyone. Most people around here have just dropped the army all together, because of the taint that army usually brings to games around here. Most people I know, friends or in LGS, play just for fun anyway.

Hordes make more sense for armies like Skaven, Goblins, Vampires, etc.  Occasionally, you'll see other "Blender Hordes" like Dark Elf Witch Elves where they can dish out crazy amounts of attacks in one go (due to the horde formation), but others, like Empire Halberdiers, want the bodies to absorb attacks while still benefiting from that extra row of attacks.  

A horde of Dwarf Hammerers can be quite the nightmare too, if you're willing to invest that many points into one unit!  (Can be really fun in large point games!)  

Hordes have their uses, mainly as a centerpiece unit. Busses also have a place, for tarpits you need to remain steadfast as long as possible. And small units also have their places too. All work together to make a whole army work, and work best.

Hordes are awesome. To me they're what the game is all about. When I think of fantasy battles I think of LARGE units of infantry fighting LARGE units of infantry. Hordes and steadfast finally made this a reality.

So much better than HeroHammer and CavalryHammer of previous editions.

Something like this:

It makes you wonder how 8th edition would've been played if Steadfast could have been disrupted.

Any army that is made not to engage is boring, whether gun line or avoidance, its a game and meant for both parties to have fun. It's not like your playing for a million bucks most of the time!
