Spread Not Working?

[mp-please]

I know it might sound odd, but since the moment I got Spread as an AST, I couldn't use it. In battle or out of it, the skill's been unavailable to me. Anyone else get this problem? Or am I missing something?

Try poking the mob with combust before using spread, if you draw a card and tank pulls you won't be able to use spread due some reason i dunno.
