We decided to try and use as many mesmer skills as we could.
No PvE skills
No consumables
Max of 3 humans.
The only secondary profession skill allowed was hard res
Could only use mesmer self heals. i.e No non attack self heals(so Illu of weakness was out)
So basically the only protection the party had was to deny the effects of the enemy while inflicting enough damage to kill them.
Tbh the weakest part of our "throw it in and see build" were the heroes, bascially we had to play 3 roles at the same time as the heroes decided to take the day off. It was'nt that hard, but just annoying.
Anyway we managed, rastigan all the way to completing the restore quest, which was pretty fun as mesmer condition removal is weak

A more synagised and more people in the build would allow completion pretty easily. As I said, nothing staggeringly hard this time around, and the concept of using kiting, shutdown and pressure mitigation is'nt new. But it did make a really nice change of pace from AoE smash bang of recent times.
