I've noticed recently on my rounds of SB that any time I get many Frost Lotus drops I find almost no Titanium nodes, and vice versa. I'm starting to wonder if there is some law of conservation of Titanium nodes and Frost Lotus.
Obviously I'm kidding but it is funny that I never seem to get several Titanium nodes and Frost Lotus drops on the same farming session, and I generally farm when the area is quiet. Of course my theory falls apart on the days when I don't get any of either...
