Guild Wars 2

My main is a Mesmer, and I am looking to swap out my vanilla +9 infusions with the stat based ones.

I typically run the Boon Share Chronomancer build, and I have a full set of Assassin’s and a full set of Commander’s gear.

For the Assassin’s set, I was thinking of getting +9 Mighty Infusions to bump up that extra power, and for the Commander’s gear, I was thinking of +9 Vital Infusions.

Reasoning:
-When I am in my Assassin’s gear, I am already on the squishier side, so might as well go for more DPS.
-When I am in my Commander’s gear, I am typically tanking a Raid boss, or doing some sort of content that requires that my Boons are far more important than my DPS, so I should want to max out my survivability (Commander’s already has Toughness, so Vitality seems a good addition to the mix).

Is that sound reasoning?

Oh, and fwiw, the Assassin gear has Scholar Runes, and the Commander’s gear has Leadership Runes.

You obviously can afford them, so the mighty infusions are a no-brainer.

Regarding the vitality infusions, do actually need the extra survivability? If you are currently doing fine, it may not be the best use of your money. An alternative would be to use the WvW infusions as a trial to see if the added vitality is useful before you commit a large amount of gold for the +9’s.
