I've just started making use of the mining skill i trained up as i was levelling and want to mine the titanium required to eventually get to the point where i can have four titansteel guardians crafted.

I've flown around wintergrasp, sholozar and icecrown and havent found a single spawned titanium node. I'm using gathere with some nodes a friend sent me while he was farming ore.

Does anyone have any tips for maximising your yield of titanium ore?

Thanks in advance.
