The amount of tears in this thread are delicious. Seriously, if you're sitting behind your computer right now and can't see the potentials of this ability (both as the druid and the receiver) and aren't able to think outside the box, then you're one of those people who will come and cry on the forums as soon as it goes live because you don't understand how to use it. Symbiosis is a perfect example of an ability that raises the skillcap of a class to the point where smart and good players will benefit and half-brain bad players will end up dead.
