Really a joke for a feral. I didn't have to do anything except for swipe spam and mangle/lacerate on boss.

This boss is a tricky one unless u know what to do. You need to clear 2 packs of trash before you fight him. The 3rd pack you can just ignored it as they won't be agroed when you fight Thekal and his guards/adds. The 2 adds are Zealot Zath + Zealot Lor'Khan. Thekal and his adds need to be killed together or they will rez up if you too slow. As a feral, just swipe and mangle/lacerate/maul them and make sure to get their health low together. Then just finish them quick qith Berserked. He will then change into a tiger, this is the easiest phase just DPS him down and get the loots. Still no Swift Zulian Tiger.

This optional boss can only be fished/summon using Mudskunk Lure and Zulian Mudskunk which u can fish inside ZG itself. Nothing hard just tank him inside water so you don't take any damage when he hab you into the air.
Another joke for a level 80, just tank an spank. Occasionally he will port you into a group of skeletons which 2 swipe will kill them all anyway.
Bloodlord Mandokir
This boss can kick your sorry ass if you don't do it properlly. You don't have to clear any trash unless you fighting him below the altar, which I don't recommed. He will fear and stun you so make sure you topped up your health.
