It appears this mob may have been changed. The affect from the tigeraptor no longer does massive damage; it is actually pretty pitiful now. But the Velociraptor spit AoE damage seems to have been increased greatly. It went from hitting about 4-7k to 25-35k and would hit people 2 times per AoE.
I find this fight to just be a straight burn as hard as you possibly can and hope you don't die instead of executing the small script that it had.
Interesting information with the "!". Kind of like the /shrug with Tantor.
