No way. Final Fantasy XIII is easily more strategic than most other FFs. Heck, if you're not careful a regular mob can destroy you.

What paradigms to use, in what order, and their timing are very important to the flow of battle. For instance, I have found that I can be "too defensive" by spamming Combat Clinic and the enemies end up damaging through my healing. Another healing paradigm worked better. Also, the way the characters move around the battle area is affected by their role, and this strategy can be used to dodge some AoE attacks.

Meh. I could go on. It seems simple, but it's surprisingly nuanced.

One more thing though--sure, there are easy, and obvious paradigm strategies to use that are safe and situational however those don't yield a very high battle rating. I think the developers were smart for measuring the success of fights as this gives the player an incentive to develope more efficient strategies.
