This updated table clears everything up.
So it looks like the only useful class for ferals is DK.
And it will give us around 3% dps?
I don't like it tbh.
Because our dps will be balanced around "feral base dps + Unholy Frenzy". But if we will have to give away our symbiosis to any other class but dk, our damage will be 3% lower than other classes dps.
Thats how it will look like:
Example1: symbiosis on DK, perfect dps balance
Mage is doing 100k dps by his own.
Monk is doing 100k dps on its own.
Feral is doing 100k dps with symbiosis on DK
Example2: symbiosis on monk
Monk is doing 105k dps with symbiosis from feral
Mage is still doing 100k dps.
Feral is doing 97k without symbiosis on dk.
I think this system is flawed. The ability itself is useless. Because if you use it, you will do as much dps as you did if there was no such ability and if you don't use it(or use it for not-dps purpose), you will lose dps.
