Hello, I have seen a problem with the mesmer boons.
The next 2 skills grant swiftness but there is a problem with their interaction.
[Temporary Curtain]: swiftness (12s)
[Signet of Inspiration]: swiftness (5s)
When you possess the first and come in contact with the second, the following occurs:
a) [Temporal Curtain] → [Signet of Inspiration]: (will add 5 seconds to previous swiftness)
b) [Signet of Inspiration] → [Temporary Curtain]: nothing happens! (you lose the swiftness after 5 seconds). which is clearly a disadvantage.
I suggest that the interaction between those skills should help the players instead what actually happens. which would be consider add the time, just like the first case.
