Nice to see a couple buffs to mesmer weapons should be very nice, but to rearly boost us for boon support alot of issues havn't been resolved.
1) (Alac build) you need like 3-4 wells to maintain permanent alacraty this gives 0 utility for any other use for example disenchantment phantasm, mantra of pain, feedback to name a few, in comparison to say Mechanist that looses 0 utility and can maintain almost permanent using their jade bot skills
2) Signet of insperation once such a strong boon utility now almost useless and the only way to make it even a little better takes me to point 3
3) Insperation traitline this traitline is so usless it may as well not even be in the game, its not bad for self healing against hard champion bosses in pve for example but thats it doesn't give enough healing to make mesmer viable in that role gives little boon support for groups and for the enormas damage reduction you take if you need 5 man signet of insperation what you gain isn't worth it
I think where mesmer support needs the help has been completly missed especaly in the form of an alacrity build, quickness may fair alot better
