Guild Wars 2

Because downed skills count as the player using the same weapon as what they have when they are alive, being revived does not break the channel.

This causes many issues- especially when the weapon skills are player displacements.

For example, an engineer using rifle tries to bandage themselves with downed skill 4. If they are picked up during this time, their rifle 4 skill, Overcharged Shot, is already partly channeled, and instantly blows them backwards.

Similarly, the ranger downed skill 2 is an interrupt- but when using sword main hand, being picked up in the middle of channeling it throws you back instantly with your evade.

Things to note- I do not believe that this is a case of spamming downed skills and accidentally casting weapon skills when picked up. Normally Hornet Sting has the ridiculously long cast time of half a second. Under the influences of this bug, Ranger just gets picked up and tossed backwards near instantly.

This seems most related to the fact that if you equip two of the same weapon type and cast a channeled skill, you can freely swap those weapons without breaking the channel. For instance equipping two longbows, and using rapid fire or barrage and using the weapon swap hotkey to swap.
