I'd definitely swap out Durburz for Groblog. The improved Fury save is pretty helpful. I'd also swap out one of the generic captains for a 2nd shaman. Groblog and 2 shamen have good synergy. The Fury saves are useful, but having 2 zones of not having to pass courage tests are extremely helpful, especially if your force breaks.
If you're going to go the horde theme, I'd also swap out some generic goblins for Goblin Prowlers. They're only 7 points, and they're +1 to wound trapped enemies, and +1 for their 2H weapon. That's wounding even defense 7 on 4s. I'd also seriously consider dropping a few models, and mixing in a couple of Warg Marauders. 35 pts for S4, 3 Att, 3 Wnds, gets cavalry bonuses and can still fire 2 shots (albeit not very good ones), when moving, or when already in a fight. Just a tremendous value for a mere 35 points.
not to mention + to their F... they can even tie up vs other normal infantry.
