I can say I'm really disappointed like most in this thread...
Since so many ground aoes will remove the bind status, Tri-Disaster will be even more useless than it already was!
Sustain was good as it was, I have no clue why they changed it to MP!
Thunder is another major point, that will heavily impact the use of contagion - but there's still no reason to choose Ifrit of Gardua!
Bane didn't really get "buffed" as the original effect stated it hits ALL monsters, it just "officially" got nerfed just there - the range might come in handy in some battles but it wasn't really that needed as it won't hit more than 3 targets to begin with...

I dunno how I should feel about the Blizzard II thingy, I mean BLM will be nerfed at the same time but they don't need to worry about mana while spamming it..... WE do!

Scholars will be somewhat affected as well since the Virus will give the super long antibody effect (which was totally unneeded as Virus was already bad enough that it got replaced immediately by another virus, even if it was inferior..). Which means, other classes like WHM and BLM should definitely NOT use virus if a SMN/SCH is in their parties, making them waste a slot too. Their Adlo will still make you get pushed back or Paralyzed even if it blocks the attack completely...

And you actually have to be careful not to overwrite a Ranging Striked DoT too early now because it will actually be possible to do so.

But hey, atleast we can dot up walls and barricades which does 0 sense... I mean try to poison a wooden box which causes their lungs to fail... uh yeah right.... definitely!
