Having not played the game for a while, i have no idea what the necro bars are (i assumed its something like what i used)...
also made it quite hard to counter something that im not sure what ppl run on each prof...
Build One:
Basically a balancedish build setup, with martyr, anti spirit and a minor snare (enough for a ritualist or sin out of range of a monk)

The Mesmer build is basically designed to include shutdown, without the ping dependence that lots of ppl cry about, as well as giving support to monks with some condi remove.
Build Two:
Similar build but a fire ele over the mesmer (more direct damage, less support and shutdown)

(i know dragon is gonna hate it, but basic suggestions of counters to the mass of tripple melee builds in the meta)
