I feel the remove condition on heal trait is really underwhelming unless combined with mantra of recovery. The vigor on shatter trait IMO is much better as it gives you vigor even with 0 clone shatters with Illusionary Persona and increases your survivability much more with the extra dodges.
While condition removal isn’t abundant in this build, you do have a built in condition removal via combo’ing Focus 5 (whirl finisher) with Focus 4 (light field). Supplemented with Null Field gives you adequate condition removal IMO.
Null field really has no place in this build. All three of my utilities are extremely important, and that is one of the reasons that I take as much condition removal as possible. In another post I discussed what food I use, and my food has a condition removal effect on healing every 10 seconds. When you stack up that effect with the trait of removal, it becomes very difficult to get conditions to stick to me. The whirl finisher in temporal curtain is amazing, but not always reliable to do.
Condition removal is of absolute highest priority in this build, simply because it is a bunker build. There is no innate defense against damaging conditions other than removal, necessitating as much removal as possible. Additionally, cripple and chill both severely impeded my mobility and ability to disengage from a fight at will, becoming extremely dangerous. Lastly, poison interferes with my healing, which is a very important component of how this build works.
Without every last shred of condition removal I can throw together, conditions start to eat this build. Remember that this build is based on actually getting hit and not dodging every attack. Many condition applying attacks have a lot of small hits, making them the ideal situation for retaliation damage. In this build, I want to tank those attacks for my retaliation damage output, and then simply be able to remove the conditions applied after the attack is finished.
I’m speaking from a tPvP perspective where as a bunker mesmer your job would be to sit on points so you don’t have food buffs and you won’t be much disengaging and such as you would in WvW. Still, a trait which removes 1 condition every 21 secs at best is pretty underwhelming no matter how you slice it, especially when you consider the alternative which is basically a trait that virtually gives you perma-vigor. It is however pretty good when paired with Mantra of Recovery due it proc’ing with each charge use, the lower recharge of MoR, and the fact that MoR charges are instant and thus can be used to cleanse important conditions immediately. Of course this isn’t a mantra build though so that is point is moot.
Since I’m sitting on points and tanking damage rather than moving around and avoiding damage this makes combo’ing Focus 5 > Focus 4 very reliable, and why Null Field is also very effective as you will sit in it for its entire duration, plus it combos into another chaos armor. These 2 combined with runes of melandru which is quite effective for short duration conditions such as chill and I’ve found conditions to be quite managable.
I don’t WvW much but personally I think this build (well, with some tweaks like grabbing Restorative Illusions) has much more potential in tPvP than WvW since tPvP bunkers play a more pronounced role. You can also countercomp in tPvP such that you can switch to this build from a shatter build when the opposing team’s strat is to aggressively attack the backpoint with classes that can defeat shatter mesmers 1v1.
