so, mining…pretty much required now?

i have both blacksmithing and enchanting on my pally on live, and i had planned on doing the same with my DK when wrath hits, but after looking at all the later patterns and seeing most, if not all of them requiring multiple titansteel bars (20 hr CD) it is looking more and more like i will have to take mining to be even semi-viable as a smith on live, it wasnt hard at all to just buy the ore/bars as i needed them and farm the primals for my skillherald, but in wrath it seems like, especially in the early stages, the money that i have farmed up for my DKs elite at 77 would almost solely goto leveling BS if i didnt have mining? is it just me, or is mining just too good to pass up on now?
