I'm assuming Skelitica would be a Bulwark / Wargod combo yeah?

It really depends on your preference, but yeah BW/WG is the basic go to, however as bdelley has stated, Scorch, Stone Skin and Revite seems to be popular variances with these newer heroes.
Definitely go defensive with Skeletica.
Here's the deal: What makes Skeletica an unstoppable monster is the debuffing combined with the fixed damage.
Realistically, the only way to stop Skeletica is to ruin him during the invincibility down time, and that's entirely possible to do if he has a WG. Give him SS, or Scorch or something to fill the gap, and he becomes basically un-killable by a lot of heroes, while still being able to kill everything around him.
Giving Skeletica more damage isn't scary at all. I could care less about more damage.
