Addons are a crucial part of World of Warcraft. Not only can you use them to help you during intensive dungeon and raid encounters, but there are addons for basically anything—auction house, professions, and gear. Patch 10.2.7 could change that.
According to a dataminer, Patch 10.2.7 could be the end of addons as you know it. They discovered addon comms are “severely rate-limited server-side” in the current version of Patch 10.2.7 (currently live on the PTR). This should render plenty of addons useless, namely TRP3, a roleplaying addon that allows players to create their own profiles that others can see and interact with. The loading speed of this addon should now last between 20 and 90 seconds, and it could take longer in areas like Goldshire.
