Battle system in MMORPG - Do you like sliding?

I am building a 3D Web MMORPG, and I am not sure how to go about the battle system, especially the sliding part.

I started with melee, and I am not sure what I think about sliding.

Sliding feels fun. It feels like I am doing some crazy skills, moving all around, but then the mobs are a bit dumb. So maybe I should make them slide as well. But I am afraid it will turn into chaos.

I was also considering adding blocks, that's another discussion...

At the moment I got this:

The char has 4 axe attacks that it performs randomly each time you click space. I like the part that it is very easy to fight.

The attack is server-authored. The server decides if it was a hit or a miss. It tracks the weapon trajectory for each animation and decides if there was a collision with the mob. Performance-wise, I was able to nail it. But in terms of using this ability in the game, I am not so sure.

Attacks have an active state where they perform damage, and some prep and cooldown time where you can't attack again. It makes attacking a bit slow, but it feels real.

And then comes the sliding part.

With this system, I can just run around the mob and slide left and right while attacking. The char is slowed down only during the actual active phase of the attack. Otherwise, it can run around, and I do.

Here is a demo of how it actually looks:

Please tell me what you think about it?
