In a old burst/ hit-n-run power +1 mesmer yes, the obvious choices to aim balance is domination/dueling.
Probabily in domination i would merge the first 2 minot traits and make shattered concentration the 3rd minor, giving a free slot to make a compeling major master trait. Also rending shatter, furious interruptions and imagined burden can not/ever compete with their other choices in their slot, they lack to be choice slot traits.
About dueling… I feel it lost popularity due to at first the nerf on vigor, and more recently the nerf on energy sigil that make its defining trait Deceptive Evasion lacking when ppl look at chronophantasma/Illusionary reversion combo or even Mental Defense in inspiration.
So in dueling i would probabily add passive endurance regen or x2 vigor effectivness in deceptive evasion.
Also the major adept traits offer nothing significant for power shatter mesmer… Probabily some trait that have synergy with on dodge/vigor that aim at cleansing/softing incoming damaging condies? And btw since we are in dueling, linking a whole condition aplication and traits (sharper images and dueslist discipline) to AI its inreliable… they should have something more to benefit mesmer at all times… Like bleeding duration increased or damage increased on bleeding foes on sharper images trait, duelist discipline is a a good trait, but pistol its not a good weapon. So fix pistol cause right now shield is a better and more versatile interrupt weapon on its #5, a more versatile and well-rounded #4 phantasm summoning skill, sword is a better choice for damaging phantasm and offers damage and mitigation/counter offensive via its block/counterblock/daze. Im not saying pistol phantasm is bad… But on a offensive off-hand weapon making 1 out of 2 of it skills to JUST summoning this phantasm is a bad skill and making a bad-bouncing no dmg cc on the other just kills it.This would be changes without changing this too much and scrambling/moving traits arround to/from other trees.
To finish i still dream about an interrupt power mesmer…. A unique gameplay/role.. ( lets be serious, thief/revenant and even DH will always be better than regular shatter mesmer for roamer burst role).
A kind of bruiser with decent solo damage and sustain but excelling at “supporting” by lockdown/disable.
And interrupt could aid defensivly by disabling foes to give our allies under fire some space to breathe or aiding pure bursting classes with a timed lockdown to land their bombs on their targets.But this build even suffers more than regular power mesmer… It have key traits spread arround many trees.. Vulnerability/damage/boon strip for stability/powerblock on domination
Fuel on dueling: blind/vigor/clone can have defensive or offensive purposes, a good thing and it fuel any shatter nuance.
Chaos have lockdown flavour traits and it feed utility skills.
Inspiration is pure defensive and condi cleanse needed to last longer in this condi/bruiser fiesta.
And chrono, even having just a interrupt synergy trait, its required to play with shield… the best off hand for a build like this… Its not quite at same offensive level as pistol but can bring defense/utility also really pays off. Its also required for gravity well, again, the only elite skill that fits on a build like this.
And ofc, chronoalso fixes many lacks on mesmer… superspeed clones to make range shatter actually have a chance to land, passive movement speed trait, alacrity that give a boost to most of skills (less good skills) to give them a fresh life with shorter CDs and access to quickness, again, give clunky and slow skills a fresh breeze with faster reactions (needed for right time skillfull interruptions – your cc interrupt skill must be faster cast and travel time than the enemy skill cast time to actually interrupt them).
It also suffers from a lack of good power based amulet.. Vigilant was a good choice… but got removed cause bunker meta… Something close to it but without that much thoughness could replace it?
Also giving a try to introduce those new HoT on interrupt sigils on pvp balancing them for it? New runes to cover lacks/boost interrupt builds?Just a few opinions… a brainstorm mostly.
Yeah dueling suffered from two vigor nerfs and one energy sigil nerf.
