Is this a bug

I am playing Deadeye Lightningspear

Often during maps lets say 6 times per hour even though there could be 2 min or 20 min between I suddenly cannot use any offensive abilities for 5-6 seconds

It's not lagging
I am not stunned
I can dodge roll
I can use healing potions

But I cannot TP or use offensive abilities

There is no debuff showing top left hand side corner, I cannot find anything in my abilities description and I cannot reproduce it, it just happens out of the blue.

Anyone else tried this? or am I missing something in the lightningspear setup which can "silience" you for 5-6 seconds, without shopwing anywhere on your debuff or abilities bar so you can see when it will end?

u have no mana ?

I am always 100% mana in this spec

Yepp it happens to me aswell

Seems like something to do with Barrage. I use Barrage with Glacial Lance. Often now i get stuck not being able to attack at all.

Happens to me as well. Amazon.
Didn't start happening until he last couple of weeks.
I have no debuffs, just can't attack. Died a couple of times, reported the bug.
No response or word about it on their upcoming patches.
Probably working as intended. Gotta put you in your place somehow, peasant

I've had this happen with shield charge. IIRC tp to hideout and back resolves (not ideal though). Wonder if this is related

Edit:
Oh you said you couldn't tp... That is weird
