In my honest opinion, that build seems too focused on the stats (mainly having a ton of armor in this case) and should be much more orientated around support for and synergy between other players. I’ll try to give a quick run through my thoughts on each part:
Most of the stats in general aren’t too bad, with the exception of the armor, which is way too high. Normally, most frontline Guardians run about 3-3.2k armor and anything above this is usually just a waste.
The traits seem to be a major problem, although it does depend on what Tier your server is (which determines the size of the enemy groups), a standard build for a lot of front liners at the moment is the 00644. The only other option I would see would be 00662, but I’m not a fan of this one since I prefer to have the extra stability from Indomitable Courage. While there are a few other variations of traits that work, they are usually for the more experienced guilds in GvGs.
Check the traits on this build out: http://en.gw2skills.net/editor/?fVAQJAWRlsApVo1CxZI8DNRCRl5MEgY+BP31BwFcAA-TFSGABAcJAQSJ2UKBHS5Rgq/gy+DG8EAKTXQAAEgbezs5NDc0je0je0j2Nv5Nv5NvZpAYSYE-w
This probably isn’t the full Meta right now, but something I just threw together quickly to give a rough indication as to how traits and stats should be. The weapons could be swapped out between Hammer, GS and Staff depending on the situation/group composition. Altruistic Healing is usually a big part of how a lot of us survive and sustain the enemy bomb. So be sure to make good use of it.
The weapon sigils could use a little work. Energy sigils work wonders, especially if on both weapons. The Melandru runes aren’t too bad, the other alternative is to use Hoelbrak as used in the build I linked above.
On another note, if you are going to change your build to something less tanky, then I would advise doing it in smaller steps of 100 armor or so. This should give you time to adjust your skill level to the new stats.
If you want me to run through the meta, or show you the thoughts behind each decision on it then PM me or message me in-game.
