Summoner got destroyed this patch

[Sylari]

Considering the Thunder change is a nerf to all magic classes other than Thaumaturge and Black Mage, you only specifically got a nerf to Virus.

There's only one damage dealing magic class that isn't a Thaumaturge though, so that point seems kind of silly.

Hell if anything it's the other way around. The virus change more significantly impacts BLM and WHM because their (non-traited) virus is potentially not going to be used at all.
