I confess: Zerging is fun. Best tag build?
Reflects/glamour most likely.
I’d go for Staff (bouncing attacks and Chaos storm, the storm also has an interrupt, very helpfull) and GS (bouncing attacks and berserker) and glamour skills with reflection. Traiting glamour also helps with veil CD^^. Mirror as heal might be usefull too, if you’re the target.
Chronomancy works, I am proof of it. Now stop asking me questions. Time must be preserved!
The chillruption build in my signature works great for zerg tagging (and temporary stopping). Just swap the runes for your traveler ones and tailor the armor to your liking.
@OP:
Try this build: http://gw2skills.net/editor/?fgAQNArdWlwzKqHVzqGa9IhJFB33nUw8lj6x1te1B-jECBoOCi0CgkIBKTqIaslhFRjV3ATxiIq2roIa1SBAz0I-w
I used this for Scarlet invasion tagfest back then. (Full Apocathery instead of Dire, but Dire is way much better)
It’s basically a full support, super tank build. On its own it has sub-par dmg, but it shines when you have the team to kill for you. Blind + Confusion will basically shut down the enemy zerg, giving your zerg the advantage.
Blind negates single-hit burst attacks while Confusion punishes multi-hit attacks (and get you lootbags with your AoE glamours). If you get focused, stealth away.
You can let your clones die to inflict conditions, or shatter them for nice burst dmg.
