Channel Skills and Invisibilty
Offhand focus with Reflect and Feedback for the win.
Reflect and vanish.
Stealth, has a problem that persist in every way in many situations, even in other games. Unfortunately, in Gw2, we have this very annoying issue of the *cast skill on target, follows thro stealth mode/invisibility.
This happens all the time with thieves, rangers, mesmers and engs (i think, not sure about this last one), its been 2 years since launch, they really should look into those “details”, but oh well, there are more concerns that require more emergency. haha :P
About the Swoop, i think it were predicted, im sorry, not saying youre a noob or any L2p issue, but after a time, really good players start to imagine where the stealthed enemy are and hit that spot with their powerful attacks.
Maybe u got bad luck, but, tell us more about your experience in pvp, is always nice to see these stories
