It could be due to all the changes to stuff from the patches since then, but that won’t really work in the current state of the game for any serious play. It might be fine for campaign, but even Ultimate would be a struggle with only 1 point each in the pets themselves.
As for the question in the OP, Blightfiend/Reap Spirit builds might qualify if you want pet builds that don’t quite feel like pet builds. Closest thing to a good hybrid in GD as of this post.
If you want more flashy stuff, try my Pet Pyromancer: Fire Birb - Pet Pyromancer
