Guild Wars 2

I recently rolled a guard and I have played some wvw with it I plan on mainly playing wvw with it. I already have other classes for damage and I want my guard to mainly have as much sustained tankiness as possible …survive as long as possible in in zvz and 1v1
Traits gear upgrade components skills strategy everything
If the build can be changed easily for group heals and boons that’s a plus
Thanks in advance

Let me begin by stating I am not sure if this is the appropriate forum section for this post and if a mod sees it I appreciate this being moved to the correct place.

My birthday is approaching and I was considering getting a gaming mouse specifically for guild wars 2. I saw several options while scanning the web for choices

Razer naga 2014 looks optimal but I am disconcerted by reviews I have seen stating that the buttons fail after less then a year
Another choice is the Logitech g6000 it is similar to the naga but some say it lasts longer and It has a g shift .I don’t know if you even need that many hot keys for gw2 though.
I was also considering the orbweaver as the thumbs as and moving body pieces seem to add comfort

The longevity of these mice is important to me because it will be a birthday present and I can not afford a replacement at this time.
From someone who hsa experience with either of these mice it would be great if they could be ranked by ease of use,comfort,gameplay utility,longevity , and personal preference
Also if you are endorsing a mouse you use then how you map your skills would be really helpful
Thanks guys
