The Lords of War series is back with Grommash Hellscream!
It seems you will be able to get more than just LFR quality raid gear from rare Garrison raid missions. Kalgan(Tom Chilton) explains how you can even have a chance at mythic raid gear:
The fourth tier is special in that they show up rarely, but they’re raid missions for your followers that reward your character with raid quality loot of a tier higher than you’re currently running. If you’re doing LFR, you’ll get normal quality raid loot, if you’re running normal raids you’ll get heroic quality loot, and heroic raiders will get mythic quality loot. Mythic raiders will get mythic loot and 1k gold.
These missions show up rarely enough that you won’t be able to deck out your character in these items before the next raid zone shows up, but having a handful of them will give you a nice edge.
Without getting into exact numbers, being classified as a “Heroic raider” or “Mythic raider” or the like requires multiple weeks of experience in a given zone at a given difficulty. And if you’re worried about the impact on gearing up for the next tier, an occasional chance at a random Mythic piece pales in comparison to the dozens of Mythic items your farm clears will be bringing in every week, with the ability to trade items around and target specific drops through bonus rolls. This will be a drop in the bucket by comparison.
Garrison missions (or lack thereof) aren’t going to impact any sort of world-first or realm-first competitions. But this system does help keep the system relevant to a broader range of players, and as overall gear levels improve over the course of a tier.
