The Sentinel Skill Warpath has a node, named Quicksilver Wind, which should, with 3 points invested, increase the movement speed by 30%. Instead, according to the character sheet, the speed get lowered. In my case by almost 12% (6 percent points)
So warpath has a innate 20% less movement speed, quicksilver wind is 30% increased. Increased/decreased are additive modifier while more/less are multiplicative.
Tldr not a bug, you will “always” be slower during warpath than during normal walking
I just see that you only see the information about the movement decrease if you press ALT while seeing the tooltip about the skill. It’s not really an excuse, but to be honest i would like that the full information is visible without pressing ALT first. Could do an toggle in the options for this.
