Currently inspiration is far the least picked trait line, which has it’s reasons. You would expect to have a decent rework on it, but rather it currently still comes out as the lackluster specialization. Support roles in GW2 are often seen as garbage or at least less useful than any other spec (unless for guardian maybe). With the upcoming specialization you will be able to spec support and damage rather than only support as it is now, though the support side lacks quite a bit. This is mostly caused by too long cooldown’s and weak traits compared to other merged traits in other specializations.

Main Issue:
The issue currently and what I’m afraid of, is that they will just adjust the traits instead of looking at the roots of the problem. In my honest opinion this would be healing power scaling on mesmer. It’s absolutely horrible. You can give a mesmer as much healing power as you want, but it will never be of much use. So if the idea of support mesmer is still to have almost half of it’s support by healing allies, at least make it so the scaling goes well with the traits that give healing power, or make it so outgoing healing to allies is increased by a fixed percentage.
The most important scaling change would be the one for mantra healing, aka: Mender’s purity (New version).
Protected Phantasm
Most traits are based on support and phantasm. As for the phantasm part I have not much to add besides ‘’Protected Phantasm’‘. I don’t see why this trait would have an internal cooldown. It shouldn’t force a player to wait 10 seconds to recast his phantasm to actually hit in large aoe fights when he resetted his phantasm with the signet healing or when weapon swapping to another weapon set. Some phantasm just don’t need the distortion and just take away the distortion for the phantasm that actually needs it. This seems rather pointless to me and should be changed to have no internal cooldown.
Restorative Illusions:
Since Illusionary persona is baseline, tooltip should be reworked to a 4-illusion heal and the healing should be AoE. Again: Main problem -> healing power scaling must be increased. It just does too few for a master trait compared to other traits across all professions.
Compounding Cellerity:
Swiftness duration is far too short on shattering to make it master trait. A fair 3 seconds would make it far more in-line with other traits.
Illusionary Inspiration:
Argueably a problem on the cooldown of Signet of Inspiration. Mostly also a problem that has been going on since release since the cooldown of most signets is far too long. I’d suggest to just tone down the cooldown to 30 seconds, making both the signet and this trait far more viable.
Shattered Concentration:
Seems too weak for a grandmaster trait to me, especially when looking at the competition it got with other grandmaster traits. Should merge with Vigorous Revelation and add another trait for glamour or phantasm skills.
