Coming from other MMO's, the part I found the most confusing was the use of the word 'potency' on skill tips.

The 2nd biggest confusing thing was how DoTs are worded, Damage over 18 seconds, Potency: 35. Ok.. so it does 2 potency per second, am I missing something? It's very unclear that it means it does 35 potency whenever the server ticks which happens to be every 3 seconds, and is not related to when you apply the dot.

Another major concern is how Astral Fire/Umbral Ice affect your potency's. I think this information should be on the tooltips (Potency: X, Astral Fire I Potency: Y: etc etc.)
