Aran is the best designed class in maplestory, and here is why.

So much of this.

Most of DS's skills lock up the keyboard so bad you can't even open your stat window while using them.

Mobility's a fraud, cause their main attack locks you in place, it's like hurricane but with a longer warmup and it skips every 9 attacks or so. And they use that type of attack in every job...

When I played DS, the mobility was pretty insane with Demon Jump. I would imagine most people try using Glide, but Demon Jump is so much better for instantaneous movement. They have the same traveling speed, but Gliding requires you to spend the time to reach max/reasonable jump height to get any good distance. I never had an issue with skill placements.
