I generally try to avoid using Summons against big time bosses. I don't know what it is, but I almost feel as though I'm cheating, like I need to feel I knew how to beat him via strategy among the characters. And then of course you don't really need them for most normal enemies, so I don't wind up using Summons much at all. What about you? Do you feel guilty at all using them against bosses? Does it take any fun away? Or do you just blast away? Does it matter which game we're talking about?
