I'm gonna assume this is a l2p issue here. Try playing the class so you can learn how to best exploit their weakness.

I have never seen anybody make this complaint before that only exceptional players can heal. I've heard people say DPS is outpacing healing but that's the only criticism I've really seen. There is however a massive impact of having a really good healer on your team versus a bad one. I don't know if that perhaps has skewed some perception here.

Ruffian scoundrel / lethality operative is what you want. They can put out an incredible amount of off-healing while still putting out more than a respectable amount of DPS. It's incredibly difficult to play it at a high level but it's possible to put out nearly the same amount of healing as a true healer and still be top DPS.

I haven't seen any patch notes yet. But from what I gleaned from PTS forum is the 10%crit is gone. From a healing point of view, the loss of crit sucks, but the magic of the set is all in generating stacks quickly for high uptime on supercharge casting immunity. That's intact so I'm kosher with any other changes.

Air punches

Sorcs having a long range stun is a bad idea. Lightning is hyper mobile for a ranged class as it is.

Use it at 4 stacks for best damage. The powerlode tactical isn't rate limited (yet) so it's possible when your poweryield is up to hit 4 stack energy bursts every other gcd. This requires you to be focused heavily of course, but the burst potential is insane.

It becomes really important in PVP to know your rotation so well that you get to a point where your rotation becomes something you can just do automatically with very little thought. You need to take the time to understand your DPS mechanics as thoroughly as possible, so check out what guides you can and do some reading. The big thing with PVP is you have to put so much focus on PVP things like surviving, situational awareness, peeling for teammates, setting up kills, etc. Not much room for learning how to play the class in that space and still be successful. As far as your set choice goes.. something to consider: the tactician set is just free damage that happens automatically. The damage is always there and always good. You don't need to think about this set's mechanics at all, so this might be useful if you're new and still learning the ropes. The Debilitator set is something you would use only if you can play the class at a high level. You need to be clever about planning your double stun window to get the most bang for your buck. The CD reduction on roll is sweet, but so much of concealment's defence is dependent on perfect player execution. If you're terrible at rolling to avoid damage, then this set would be a bad pick. If there is any chance you would go lethality then you would for sure want to get tacticians. Debil for lethality isn't as good as it is for concealment.

If you want to be competitive at the highest levels of PVP you need a comprehensive understanding of every spec in the game. This includes debuffs, defensives and how their burst windows operate. I'd suggest if you want to go down this road to either play every class or read up guides for every class. This way you know exactly how to respond to anything your opponent does.

There are two problems that I see here. If someone can die in 4 seconds then you're doing something horribly wrong. You're not using cooldowns you should be. It also sounds like you're not using the cc breaker correctly. If you're using it on the first stun then of course you're vulnerable to a second one. Two stuns with multiple people attacking you is generally checkmate in most cases. That's totally fine and not supposed to be an encounter you survive. You need to save the cc breaker for the second cc when it puts you at full resolve. The other thing I see is if you drop the duration of cc you will never kill anybody. At the highest levels of PVP you won't be able to kill someone before a healer will intervene and save them. You need to anticipate if a double stun is coming and counter it with defensives or peels for your team.

I'm not entirely sure it's you. I levelled up my sniper alt to 75 and geared myself in optimized gear and found myself getting wrecked in PVP. I went with engineering and the damage felt too weak and the survivability was pretty meh. I don't think the class is at the same power level it was at 70. I think the class may have been left behind in the 6.0 arms race. I will admit that I don't play my sniper often, but perhaps some players with more experience at 75 could confirm my suspicions. It seemed to me like it wasn't worth playing over the other choices for PVP.

The damage is strong but the class has a very high skill ceiling. It's incredibly difficult to destroy people so comprehensively unless you are against defenceless bad players. I can't see anybody stepping into this class and on their first try be so dominant. That shouldn't happen playing with competent players.

What are you taking about? His post was well written and dead right. Burst is king in PVP. My post was just a meme, but viral elements burst window is flying under the radar for how much damage it is doing.

/laughs in viral elements tactical

Well I do see snipers, but I see noticeably less than I used to prior to 6.0. The one's I do see are all playing marksmanship in PVP and I almost never see engineering. I see virulence is the best parsing spec but never felt the spec was good to use versus competent pvpers. Was your experience playing engineering similar to 5.x? Any better or worse?
