I still hear people say how rare those Titan Drive Components are, but I still keep finding one each time I go looking.
I don't look specifically for that one component though, but collect a lot of other things too, and in the process I think I am covering a lot more ground than others might. Not sure, but I keep finding those parts pretty easily.
I do think collecting everything helps force the spawn, and in turn increases the likelihood of finding a TDC.
I'll be putting your theories to the test soon. Wish me luck guys
