Shatter enchantment is weak unless there are multiple mesmers in a group (2+). It recharges every 25 seconds, and it's one out of the 2 offensive skills on the shadow mesmers which means they are going to continually cast it on you on sight and as soon as it recharges.
I havent been using the old build with 2 covers to protect protective spirit as you can see. I just let them shatter spirit bond every 25 seconds and re-apply.
You can kinda sorta use the recharge timer on insidious parasite to know when the next shatter is coming and refresh ps, sb in that order and just make sure you notice the shatter.The I.P. timer isnt a good idea if you are using faster cast and recharge items so I usually just count to 20 myself and re-applly PS,SB, keeping insidious parasite on a warrior that is attacking me so the burn from incendiary bonds doesnt do ya in when you catch the shatter enchant on spirit bond. There's really not awhole lot of mesmers in the first area to worry about "ah man I gotta count in my head" so it's not a big deal.
The mesmers die ridiculously fast with or without a monk. Even the shadow mesmer , 2 shadow monk, and shadow warrior group by where rastigan initially stops after killing the first group of rangers and aatxe by the tower of courage gets stomped pretty fast with new build. They used to take about 4-5 mins to wear out with old build. You will have to survive multiple shatter enchants from the same mesmer but that really isnt a problem once you get the hang of it.
Took out the first group of skeletons with the 2 ether breakers, 3 icehands couple days ago fairly easy. Now those are hard mesmers to kill w/o spellbreaker or smiting skills

e-surge, cry of frustration, chaos storm, shatter enchantment, multiple maelstorms at once with snares. Tons of fun. I usually avoid them at all costs. With spirit bond it was so much easier.
