The update of "World of Warcraft" 9.1.5, in the absence of new content, players are still full of expectations, Blizzard also made this transitional version a major version of the update! In terms of updated content, players expect not new content, but the mechanics of the covenant to make players have a better game experience. However, the optimization of the new mechanism also has a bug, in principle, it is not a bug, but the imperfection of the mechanism optimization, the player can quickly brush the prestige items of the heart energy and Luo Suier, and Blizzard had to quickly fix some of the mechanisms.

The 9.1.5 change to Ghisha focuses on the fact that rare monsters can repeatedly drop "Compilation Studies", which will allow players to spend more time brushing Rares to increase Rothsuir's prestige, and to obtain Compilation Studies to upgrade or obtain items such as mounts. Going from a daily drop to a repeat drop means that the player can complete the previous few days of goal in one day, which looks more livery, but allows the character to grow quickly to save time in The Cessia brush, which is a good change for the player.
On the first day of the new version update, Meswear players easily found a way to quickly brush the compilation research, the principle is very simple, that is, focus on brushing the observer Yorick of Thea. Yorick's refresh mechanism is different from other rare monsters, Yorick can be said to be "instantly brushable", do not have to wait for too long refresh time, and the lower the reputation level of Luo Suier, the more rare monsters drop holy relics, which allows the US server players to stay in the rift all day after the version update to brush Yorick, quickly increasing the reputation of Luo Suier and getting a lot of compilation research.
The development team let The Rare Infinite Drop Relic of Kerhia, but left a loophole for Yorick to quickly refresh, and the actions and results of the US costume players were undoubtedly unacceptable to the development team! In less than a day, Blizzard quickly fixed the bug, extending the refresh time for observer Yorick. After the hot repair, the observer Yorick's refresh time is unknown, it should be similar to other rare monster refresh mechanisms, the national service players in the version is not updated when the hot repair, perfectly missed the opportunity to quick brush compilation research.
The new version allows for quick changes of covenants, and merchants at Olipos Flying Point have added Fame Boost items that can raise the Covenant's Fame to level 40. When Fame rises to level 40, the character gains 1000 Mental Energy, which is the initial resource for the New Covenant. Heart energy can be mailed to other characters through npc's packed items, which allows a character to quickly obtain a large amount of heart energy, as long as the trumpet is enough, each character can instantly get 4000 heart energy at level 40 fame.
At present, some American service players have obtained tens of thousands of heart energy through the fame of the trumpet, which is not a loophole, because enough trumpets are needed to get the corresponding amount of heart energy. And you need to concentrate your heart energy on one character, which is equivalent to giving up the initial mental energy of other characters, and players with only a small number of trumpets cannot copy the gameplay, depending on whether the development team will think that the player's rapid acquisition of heart energy is one of the bugs like Yorick.
In short, the new version of the change will always be accompanied by a certain number of bugs, such as the legion version of the regimental single brush, as well as the single brush bfa version of the island adventure, these new changes based on the old content, will inevitably also find bugs with the player's in-depth experience. But bugs that make players feel harder are generally not fixed quickly, and the mechanics that make players happy will soon be fixed by the original abuse of the mechanism!
