Wow, looking at the date of these post, they're pretty old :) Well, lions and cat like mobs are no longer kos to us rangers and druid folks :) I guess somewhere down the line they made a patch to fix our faction with em :) Now we only have to worry about the griffins...
Oh yeah, they're kos to druids. my 14th level druid got blindsided by one. i was talking with an npc and couldn't find the thing. Was at half health before i could get out of the camp. they hit for over 30 a pop
I met up with one of the matriarchs and it was "risky" (low) blue to me at level 16... so they sure aint limited to level 12.
Being a Druid and formerly a Ranger i can say for certain that all lions are aggro and KOS to both (although i'm not sure about Druid... by the time i got to their lands they were already too green to be that suicidal hehe)
I am a ranger of Tunare, and every lion I have ever seen has been hostile, ready to attack. All the other natural critters think I'm pretty nifty though.
