Guild Wars 2

Though you might have to get used to it at first, it’s fun!
This would allow some new fun content:

Events: -

Mini-games: e.g. (be it player-made…) take WvW: We’ve got Asura-Soccer/football. why not Asura-Ice Hockey?

Jumping puzzles: Yes, this would be quite troublesome for some but it’s different than jump here, jump there.

Combat: I’m not sure if there are still a lot of stationary skills but this effect would allow you to run up to a foe, use the stationary skill, continue sliding, see the skill’s effect, slide further along and possibly evade your foes’ attacks (without the use of endurance) (I think some ’’volley’’ attacks used to be stationary, otherwise think of Barrage or a guardian’s Empower)

and last but not least:
Exploration:it would add some variety and life to Tyria and the exploration of it.

possibly more could be added as well such as slipping if you’re trying to turn too quickly while under the effects of swiftness or any other movement speed enhancing skill? (I wonder how dodging would go then though )

Noone with an opinion about this?

Let’s keep Super Mario 3 effects in SAB, imo. Of the things you listed, the only thing that would be cool is the use of stationary skills while moving. I’ve seen something similar in another game where it was called “Cast on the Run”. Really nice for finger wigglers, but it was usually a buff that was specific to a certain fight/zone. Doesn’t have anything to do with ice effects though.

… where does wvw have asura soccer/football?…

I think the ice in Kegbrawl should be made slippery like this.

Slippery ice during Wintersday in WvW would be awesome, as well. Imagine the hilarity.

Asuraball!

Keg brawl with icy ground. If they add observable mode to keg brawl that would be very entertaining to watch.
