She is just too slow. 

And glad she is.

We don't need classes to fast. It starts to be an issue to see most classes being insanely fast because people wants to be Flash McQueen.

Most classes need to be nerf on their actual speed.

She's not that slow, lol. You'll get used to it after a while, if not there are a lot of fast paced classes to choose from.

I see this time and time again, and inevitably, I'll group up, and somebody will comment, "I didn't know Guards could be fast." It's certainly not a mobility class, but (as an Awk Guard) once you learn which skills in her kit move her butt, you can move from pack to pack really efficiently. Her leap skills into a Jordyn rush followed by a slide, and if needed, a Phoenix Dive, can move her long distances pretty quickly. 🤷🏻‍♂️
