It's been like this for a while now. Before it was a 23 hour cd.
Another thing I didn't see in the patch notes - all transmute cooldowns are up at midnight now? They used to be random up to 24 hours. Now it's only once per day no matter what? I was mostly OK with the lousy proc rate since I could get a cooldown refresh of 2 hours or 4 hours or whatever. Now with once-a-day transmutes and lousy procs I'm a sad panda :(
No, they were always at midnight. It was never 4 hours, it just happened to be the time to midnight realm time.
Now I'm interested. The proc works out to be the same - assuming you can only single proc on Transmute Living elements. As far as I know, double, triple, quadruple, and quintuple procs are possible on Truegold transmutes and elixirs/potions in the appropriate spec, just as they were in Wrath of the Lich King's alchemy.
Granted, I haven't had any flasks made, or any potions made, or any elixir mades, and have not seen a proc of more than two on Truegold yet. However, I've mainly been using Transmute Living elements because the materials are worth more than truegold straight off the auction house, so you have to farm them and take an opportunity cost unless you happen to get a proc. So has Transmute: Living elements been singled out so it only ever single proc'd before this change? Did it have to do with the mechanics of proc'ing several elements at the same time? Or has all multi-proc'ing been removed from transmute alchemists, or alchemists all together?
I'd also like to see Dreamcloth reset on tuesday, as well as Guild XP, so everything can just be weekly. (Asking for a number of "charges" on daily heroics is probably pushing it and everyone would get them done tuesday anyway). On that note, Guild Battle Standards don't work on [daily] quest turn ins (Mobs don't give very much rep, tabard has a cooldown and can't be moved throughout the instance) and it doesn't count toward guild rep. Pretty much pointless.
