As you put your hands on all these new skills with the arrival of new weapons available for each core profession, and these attempts at balance, why not give a breath of fresh air to a skill that hasn't been modified since 2013 (certainly not because turns out to be perfect). I'm talking about Freezing Gust in focus #4, perhaps taking a cue from the homonymous skill of the original Guildwars, for example:
Freezing Gust ½ AT 20 CD
Chill your foe for a brief time. Deal more damage to chilled foes.

Chilled (5s): -66% Skill Recharge Rate, -66% Movement Speed

Freezing Gust ½ AT 20 CD
Chill your foes for a brief time. If those enemies are already Chilled, apply Slow as well.

Chilled (5s): -66% Skill Recharge Rate, -66% Movement Speed
Slow (3s): Skills and actions are slower.
