Iv'e been getting back into GW the last couple of weeks and found that there are quite a few things about mesmers that aren't the same. Been going mostly to RA, since I'm not currently in an active guild.
I used to love mesmers becasue of the huge variety of useful builds, but as it is, I have really only found one that really does the trick for me on a regular basis.
Rest Fast cast
Signet of midnight
The reasoning is that a) There are alot of toons that do attack damage in ra nowdays. Empathy hurts them or stops them and sig of midnight is a perfect self defense. A defensive stance is almost always needed as well.
b) Backfire, Diversion and shame/guild is enough to give casters a headache. c) Blackout is usefull all around.
Energy is fine since there are no real spamming skills and since people tend to cast through shame/guilt.
This build does usually work fine, but I'm feeling it's a bit of a multi-tool without any real edge. However, when I do try to specialise in for example caster shutdown I always end up dead at the hands of an assasin, warrior, dervish etc. I would like to have viable alternatives, that are not to fragile and that can be more viable in really shutting people down and what not, not just beeing a nuisance.
