Honestly, I kinda suck at setting up "decent" builds for people >_< I'm pretty sure the Mesmer community would rip giant holes in any setups I currently use lol. I have a very odd play style on my Mesmer (at least I'd say it's odd compared to how many Mesmers run out there in WvW and PvE!) - a play style which I guess has suited me over time. Having said that, I am currently working on several different build setups / play styles for Mesmer which I am playing with. Primarily because I have had a number of requests for help with Mesmer builds, so I realised that I need to actually learn to put together viable builds lol! And secondly because I need to start trying other Mesmer play styles which will better enhance my commanding ability out in WvW!
I will be happy to share them with you all once I've tweaked them to my satisfaction, and I will value and highly appreciate any feedback from fellow Mesmers on them - both from just looking into them and from working with them and giving first-hand experience feedback on how they play :) Keep in mind I am new to putting builds together, in general, let alone for others, so I appreciate you going easy on me and be kind about whatever I do post - there is a good chance that the setups I am working on will need a lot of optimizing and help from my fellow Mesmer family :)
Also, as Sek mentioned, with the upcoming changes in September, I too am holding off giving out any new builds / ideas until I know more about the effects the patch will have on our traits and I am able to re-work them accordingly. There are a few changes they have mentioned which I'm excited to try out. I will keep you guys posted and hopefully have some ideas / setups for you to try soon after the new patch :)
