No, it's not insulting and it's not nonsense. Keep reading, though, before I lose you on my first statement.

I don't know about you, but in previous FF's all I did was attack, attack, attack once I was at a high enough level. Sure, when you're at a high enough level in FFXIII, you too can do this, but ideally you'll still cast things such as Haste etc. first, so it's got a bit of thinking to do. So either way, there's not much thinking to be done. However, if you're going to fight things earlier on, you don't have the simple options. You make do with the jobs you have available to you up until around chapter 10, and sometimes those options aren't favourable and you have to come up with alternative strategies. And even when superpowered, you still tend to need to know what you're doing if you want to get five stars against some of the harder monsters.

I'd say I thought far more during FFXIII battles than I did during VII, VIII or X. XII possibly required some more thought for particular battles, mind you. For FFV, which I've been playing recently enough, I just attack, attack, attack through most battles, too. With any job, too. If you want to level up four white mages you just put barehanded onto their second job thing and unequip whatever and go hunting, no problems will be had at all. It's a walk in the park. Strategy, as I said, mostly goes out the window when you can level your party as much as you like. With XIII, they restrict that so on occasion you will have to think things through. If the thinking is quick and easy for you based on your experience of FF enemies, then good for you, but that doesn't mean they're that much easier than previous FF's, just that you already know what to expect.

EDIT: I will concede absolutely that Reflect allows for a dramatic increase in potential strategy, however I will also point out that you will rarely need it. I only used Reflect on about one battle in each previous incarnation if I recall correctly. It may have been useful in other areas but when you can just attack for buttloads to begin with and walk through your enemies after you've been gil hunting for a while, it's not worth the waste of MP.
