Sigil of Leeching and Death Shroud
You’re not missing out on anything unless you are in shroud for sub 10s and for some reason can’t swap after leaving. That said, I do think these kind of things should work through shroud.
What? Swapping into Shroud procs the Sigil if it’s not on cooldown, consumes the sigil and does not heal you. The only way you are not “missing out on anything” is if you weapon swap immediately upon Sigil CD, and then promptly pop into Death Shroud. This is not exactly optimal, and largely restricts Death Shroud use if you’re looking to gain back that thousand HP.
And you weren’t going to be proccing it if you were in shroud anyway. So the only time that this actually “costs” you the healing is if you go into shroud, consuming the proc without healing, and then leave shroud and weapon swap, all within 9s of first entering shroud. If you stay in shroud for at least 9s, you’ll proc it again on exiting, if you weapon swap before there is no change, and if you weapon swap after 9s from entering shroud there is a net gain. In most situations you’d have to go out of your way for it to be a loss compared to not proccing the sigil at all.
Ah, I see what you’re saying. Assuming perfect scenarios, yes, I believe you would be correct.
As it stands, however, the healing component of Sigil of Leeching is an enormous reason to actually use it. This means that there are times where the Sigil will be off of cooldown, since you have had no reason to weapon swap prior. If you need to heal with the Sigil, you can not enter Death Shroud until you first weapon swap. Otherwise you do not get the heal.
“So the only time that this actually “costs” you the healing is if you go into shroud, consuming the proc without healing, and then leave shroud and weapon swap, all within 9s of first entering shroud.” This happens often in less than ideal situations.
“If you stay in shroud for at least 9s” This does not.
But at this point, I feel like it is more arguing semantics.
The issue is that the Sigil can potentially lose a large component of its use because Arenanet implemented a mechanic that was intended to benefit Sigil users. Not hinder them.
