Nah, levelling's good. There's a few places after the events at Raithwall and later after the events at Bur-Omisace that are really taxing if you haven't leveled enough. While clearing each area of each location might seem like a lot sometimes, it's not enough to see you through. I found both Ozmone Plain and the Phon Coast to be rough going even though I thought I'd levelled up enough.
What really irritates me is the fact that I need to go up another fourteen levels before I'll be ready to face Zodiark and stand a chance (I was doing well the first time I met him ... until he used Growing Threat; I didn't even make it to him the second time, but I had tried to flee all the way to his arena). That and trying to survive the Subterra to get to Ixion and Shadowseer, slaying the King Behemoth and Hell Wyrm, not to mention unlocking Omega Mark XIII and Yiazmat. I'm just not strong enough on level 57 with Bubble Belts on all but at this stage it takes forever to level up.
