Energy Management on a Panic Hero

Having the Wastrel skill is counter productive,you WANT them spamming their skills so that the interrupt everything so it's a waste of energy really. It's all about synergy. Panic and Psychic Instability are like the most broken mass interrupt skills in the game. I don't have to explain you that most builds are build around an elite skill with synergy in mind. When the foes are doing nothing, getting interrupted or are lying on the ground you would want to use skills that benefit from that. The most noteworthy are WW, WD and WNWN.

Using something like overload in combination with a lot of interrupt skills isn't a good idea cause it's counterproductive. Btw you might wanna add Mistrust to that build, the skill is insane as previously mentioned.

It's a shame the AI sux, Fast Casting also seems to be the hero mesmer's own enemy in this.

Yes the energy usage needs to be worked out. Has anyone tried Drain Delusions? They'll occasionally rip a mistrust but otherwise they're quite reliable about spamming it. But again I typically don't run WW, which will wipe their energy extremely fast.

I find there are near always enough interrupt targets for cry or even overload to still trigger with the hero's absurd AI. There's always one guy in the mob panic fails to interrupt and your mesmer can still nail him. Just mind that you're doing this for the side benefits - damage or energy - because the interruption itself is kinda wasted.

Thing is - with Panic one guy in the mob HAS to get a skill off, or the other guys won't get interupted, its like the pay off you have to accept. Im going to try Guilt.

No chaos storm love? ... Glyph of lesser energy? why not waste not want not? Because I saw that my Gwen rarely had a chance to use it. Even the PvE Casters are always either casting or wanding. GoLE can always be used and has the potential to save me 14 energy overall (if both the spells are 10e - both are reduced to 1e, thats 9e saved each, minus the 5e it takes to cast thats 14).

And chaos storm, well I just haven't found space to slip it in!

Well, I've managed to find a build which pumps out pretty decent damage, disruption and can maintain her energy really well:

Panic [E]
Wastrel's Demise
Mistrust
Signet of Weariness
Drain Enchantment
Power Drain
Guilt
Glyph of Lesser Energy

Once we get 7 heroes, I'll be switching out Sig of Weariness for Unnatural Signet - but currently I've replaced my MM with this Panic bar and I need a replacement for Enfeebling Blood. I'm sceptical that this build does pretty decent damage - it's got a grand total of two offensive spells and 4 energy management spells.

I'd be inclined to drop Signet of Weariness and Guilt for Leech Signet + something else, perhaps Unnatural Signet if energy is still problematic, or a more powerful damage skill like Cry of Frustration or Shatter Hex if energy is fine. In the meantime though, it looks more like a defensive bar than an offensive one.

The damage really adds up when WD + Mistrust are being used on recharge (which is very often considering fast casting and that shes using a 20/20 set). I have just finished Grothmar Wardowns HM, an area which has caused me trouble in the past due to the strong Charr groups. Gwen had no problem dealing with the flameshielders and outdamaged the healing from the menders/prophets.

I will admit that atm Gwen isn't as offensive as I'd like her, as I say - I'm swapping Unnatural Sig in there once I find a place to slip Enfeebling Blood into my hero setup.

Panic
WW and WD are really unreliable. I would also include Mistrust as also unreliable, it will likely fail from the foe's build or profession.
