This little tidbit caught my eye on MMO-Champion yesterday:
Transmute: Titanium no longer has a cooldown!
I thought it was interesting because it should drop the price of titanium ore, titanium bars, titansteel and possibly crafted gear that uses titanium bars. Another thing I think it will do is increase the price of saronite ore and bars. It may also make Transmutation specialization a bit more profitable. On Bleeding Hollow, the price of a stack of saronite ore usually bounces between 15 and 20 gold. Find a reliable miner to smelt your stack of ore that you purchased for 15 gold and your cost per transmuted titanium bar is (1.5g/bar * 8 bars) a whopping 12 gold. I'd say there's room for some profit by selling individual bars to the masses.
I have a feeling Blizzard is doing this because they are going to introduce a few new high end alloys that will be used to craft Icecrown level gear, similar to Felsteel or Hardened Adamantite back in the Burning Crusade. If they do, I'd bet that these alloys will require titanium bars. I've already read that there will be something called Primordial Saronite, but haven't seen any details of how to make or buy it.
For those who have a stockpile of titanium bars, it may be a good idea to start liquidating your stock before 3.3 hits and you end up taking a big loss. I'm not quite sure what will happen to titanium ore. It will most likely take a slight drop in price as miners won't need to buy as much (or any) of it to make titansteel, leaving it to the jewelcrafters, which will most likely keep buying as much as they can to prospect for epic gems and powder to buy jewelcrafting tokens with.
