Comments, and a few Blitzball questions.

The Al Bhed are the most difficult team to contend with at low levels, with the Goers in second place.

And what did you mean by it can prevent me from getting Brother?

Nothing can prevent you getting Brother. I think Tavrobel meant if you level up lots now you'll miss out on Brother's domination of the field at the low levels. There's nothing to worry about though.

So its bad to play Blitzball at this point and I should revert to my earlier save.... or its ok and keep going from here?

If you've already won Attack Reels then carry on playing. There's no need to start over from your previous save.
