Best burst class?
Well if you can get a Killshot off, there’s not much faster than instant. Eviscerate also does a fair chunk of damage, especially if you follow up with a quick attack afterwards.
Consistently though, Thief is likely the best, if you crit, you can get well over 15k damage in about 1-1.5 seconds, and it can be started while stealthed, which is much less obvious than the decade you spent knelt on the ground for Killshot.
killshot is followed with a 100Blade will proberly get your target down if the killshot is not reflected back at you(and that is very likely if they can they will), then there is the thief with bs burst. but all burst is to some degree easy kills for others with a fair amount of skills where thief is the easy way to survive also

Thief or mesmer, especially 1v1. most competent players will be able to get of your 100blades or see your killshot coming.
The difference is thieves generally do there burst right away. If it hits, you’re done, if not, reset fight and try again.
Mesmer usually needs a bit of time to build up, spawning clones, phantasms, placing, etc, then burst at the right time.
shatter mesmer or s/d arcane ele imo
80 warr [Blaze Steelsoul], 80 ele [Blaze Nightstrike], 80 mesmer [Grim Shatterwhirl]
80 guard [Dusk Grimlight], 80 engi [Flintgear]
spawning clones and tasms arnt the problem, the problem is luring or stunning and having the reaction to re-supply the clones for a frontal assault before the stun / root expires, likewise if your fighting another competent player they will dodge roll the shatter, so you have to ’’fake’’ it to make it.
there’s more to mesmer burst than meets the eye at first glance though yes its very powerful.
remember you can kill fast but will be killed fast so be vigilant, also mix zerker / knight / cavilier + boots as valkyrie and you have a very good burst / toughnes / vita ratio, enough mitigation to survive burst and enough burst to burst anyone down.
