I mean that the proper reference client would be 1.12, which we know for a fact still works properly on modern PCs. The Legion port should be emulating the original client as closely as possible.
Nah, you’ve got the right concept. I was a little confused as well, but I think Blizzard has been using it as a catch-all term for the game client, database assets, etc.
There may be some. While memory is obviously fallible, I don’t ever recall hearing of or experiencing mobs hitting 5+ times in a single swing after being kited, which has been resulting in one-shots. According to wowhead, thrash should be a proc, but I have mind controlled mobs that have thrash. It’s currently coded in as an active ability. Methinks Blizzard wasn’t able to code in the proc properly and therefore made it an active ability with a cooldown.
