Tips for Festergut and Rotface
Festergut and Rotface suck. They are hard bosses and require each and every raider to give 110%. Each player needs to maximize the performance of their role and minimize anything that hurts the overall team effort (especially avoidable damage!).
Here are some dopey little tricks you can use to bring your A game to each fight:
1. Use a slow dps weapon for Festergut
Considering how tight the enrage timer can get, dps from every member of your group matters, and as Paladins we have the luxury and privilege of contributing more than our fair share of tank dps to the pile.
While Festergut may hit hard, he only does during a small window of the fight. Assuming you have the defense to spare, don't be afraid to use a slow dps weapon (the slower the better) to maximize your damage. The slower your weapon is, the more damage each 5-stack proc from Seal of Vengeance/Corruption will do.
2. When not tanking Festergut, stand behind him
You should be soft-capped for expertise anyway, so to maximize your damage done on this fight, stand behind the boss to avoid causing parries for yourself and the person currently tanking.
3. Make the best use of your Gastric Bloat buff
Let's combine points one and two. When you hit 9 stacks of Gastric Bloat and get the boss pulled off you, jump behind the boss, cancel Righteous Fury, self-cast Hand of Salvation, pop wings, and go to town.
Doing that in the ten man last night, after my tank switch I ended up pushing little more than 8000 dps. You can see it after that second huge dip in my dps, I slid behind the boss and immediately exploded in damage.
4. Make sure to Judge when kiting the Big Ooze
Judging is an important part of keeping threat on the Big Ooze while kiting. If you're just shield tossing every 30 seconds you're going to find the healer aggro riding hard on your heels. So, you definitely need to judge when possible.
The easiest way to manage Judging without getting murdered by being too close to the Ooze is to run ahead of it (as you would normally) until you're just out of range and the Judgement icon is red on your bar. The millisecond it gets color back, click it/hit the hotkey, unleash your Judge, and then keep moving.
You can also use the range on Judgement to safely gauge your distance from the Big Ooze.
5. Use Seal of Righteousness for Big Ooze kiting
Seal of Righteousness will give you the most threat bang for your buck. Since you won't be able to get close enough to build a 5 stack, Seal of Vengeance/Corruption is useless. Moreover, Seal of Command is only really good for aoe situations.
Thus, the burden falls on the neglected Seal of Righteousness. Each time you judge with SoR you'll do more threat than you would judging any other seal.
These are very good tactics. Thanks for finding these Pat.
