Bump. Can we get a reply from Plarium on this issue? She needs to use her turn meter reduction definitely, and peppering in A2 when it's available may be good too.   

Wow, I was just on the way to build one SB for the Spider on my second account. Now i need to investigate is that the case for every set up or she use those skills if there is specific debuffs or something.

Can you tell me your other champs from your spider team? 

Any update as to why?

My soulbond is doing the same thing what’s pretty crap.

I think if you click on the spider (so the spider shows with the crosshairs under her), SB will use her other skills.
