Yes. I made the exact same switch that you did - albeit, I'm L65, but I think I can safely say that it's the best choice I've ever made. IMHO, Glaviers are just repetitive boringness - SSS + Mars, at your level. Anything else? I doubt it. And if you ARE using any other skills, you're grinding the wrong way. Bladers, on the other hand, require more skill to play - when KD's are appropriate, and how to time your Stabs correctly. When to use Chains, and do I level up the Smashing Series or not? The sexy weapons, the backflips and stabs - there's no arguing that Bladers are certainly more entertaining to play than Glaviers.
And besides, you've probably had the pleasure of trying to fight a Blader, or the displeasure. And not being able to kill him. I thought it'd be fun to be on the other side. And oh, oh, it was.
Made a thread about it when I did the switch. Take a look if you want:
