Protective Statuses, good or bad idea? Options

[Nintendoshs]

So, in my newest game i'm making in rpg maker 2003(Battle world is the title.) I have so many custom features for fights and storytelling. I needed something for conditions so I added a skill that blocks all meele attacks for 3 turns, I added versions that protect for 1 and 2 turns. I also madde a version for skills. I want to know. Is it a good idea to have these skills or is it a bad idea, making the character OP'ed.

I say that if you want to use spells like that, they need to be really useful, otherwise I doubt the player will use them. For instance 'Haste" in most Final Fantasies is a waste of a spell. It doesn't grant that much of an advantage, or rather, the advantage is negligible when you can win just as easily without using the spell.

So if you can work it into the fundamental battle strategy, I'd say go for it. But if it's just something "useful" the player could do, I wouldn't bother.

Greatly disagree, giving options is a good idea, it allows players to come up with their own battle strategies. I, for example, use haste quite extensively in games because I value being able to speed up a victory, even though it'd takes the same number of turns, one more even since I had to cast it in the first place, but overall its a faster battle, that is my play style that couldn't happen without that choice.

In terms of protection spells I rarely use them, but if I had that one you're proposing in my arsenal, yeah I would. But only because, like others have said, its overpowered. You'd be a fool not to use it really. And that's the trap, its so powerful a move you would have to use it, you just would. It would become 'fundamental' as Ennaya puts it. Really, I think number of turns is the wrong variable for this.
Think of Pokemon, the protect skills on there are only for one turn. The absolute opposite so it must be right, right? Wrong. They are absolutely useless unless the enemy's using a two-turn attack that requires powering up on the first turn. If its used at any other time then all it accomplishes is stalling, because no-ones harming anyone.
So what are your options?
Well I'd go with one that caused a continual mp drain to maintain (differs from a oneturn defence because you'd still be able to use other attacks).
One that massively reduced other stats (if it continues to be a three turn affair).
You could even go Yojimbo with it and have a shield that cost money to maintain (something I always find interesting as money rarely features in battles).
