Aero isn't cross classable as summoner though, I was sad when I found out at lvl 30. I haven't tested ifrit and garuda damage so far, but I've noticed that using ifrit makes me drain mana (Sustaining Thunder, Shadow Flare, Miasma, Bio, Bio 2, and using ruin 1 as filler (cheaper mp cost than ruin 2) a lot faster because contagion isn't available to ifrit. With Ifrit I have to use more energy drains to maintain mana, and more endrains mean less Festers. Contagion as someone pointed out, can have a max potency of (40+35+35+35)x5=725 potency, which is quite hefty for something on a 1 minute CD. Either way, it's a new class and the parser may seem to have issues recognizing dots, but it doesn't feel that we're so terrible that we're not worth bringing to parties.
