It probably won't cost a couple hundred in NX. I think it'll just be closer to $100 at most, even with the runes and enchant scrolls. 200m is a lot of spending money.
Anyway, that's the mid-tier "regular player" set. The Mhara set I mentioned is the super rich set and it basically plays out the same way, but instead the base price of the armor jumps up dramatically. I honestly wouldn't even bother with Mhara unless you intend to WB/F it because Wonderland could do do similar things a lot cheaper and still give you a lot of money left over to spend on your weapon or whatever.
Always go for a level 70 weapon before any piece of level 70 armor. The value of the weapons is far higher. Only get level 70 armor if you're prepared to afford everything. Level 60 armor can be gotten right away because it's a considerable upgrade from the crappy 60's and other armor below it.
Well for me it was that since I'm terribly inefficient with money. XD
Anyways, that sort of set can be considered "regular" if you consider regular 14k M.Att and the ability to constantly get around 20% damage in most of your raids. So it's actually a really nice set.
Regardless, with 70s out now, most 60 things are technically obsoleted. There's only one other reason besides cost to not go for a 70, and that'd be if you already own a +12 or higher. Those weapons will beat a +10 Lv. 70 weapon, which is the best you'll get without actually having hundreds of dollars of NX and 1B or something.
