Correct, there are bugs that have been fixed and more that will be fixed. The things you and others have been relentlessly complaining about have already been confirmed to be working properly.
Leeway, for example. I’ve already shown you plenty of videos that prove it’s working properly along with Blizzard’s own tests and confirmation that it’s working properly, yet you still claim it’s not.
If they released their reference client, spell batching and leeway would be the same. The things people hate more than anything would be the same because Vanilla wasn’t perfect and had some really stupid systems that we could have avoided being implemented if you people didn’t scream “No-changes” and praise Blizzard for recreating garbage mechanics.
471 upvotes on that spell batching thread. You don’t see my upvote there, because I’ve been against the Vanilla spell batching ever since I remembered how awful it was.
