(Question) Steam > to PC + HeavensWard

Hello all just question i really didn't see around so i thought i ask.

I bought FFXIV:ARR CE on steam, it didn't even cross my mind that i would have to wait until May of 2015 to get a Pre-Order of HeavensWard CE on Steam, (I have not seen info that HeavensWard CE on Steam will be 100% the same as Pre-Ordering it right now from SE website.)

So my question is if i where to Buy FFXIV:ARR + HeavensWard CE for PC (NonSteam). Could i even add these to my mog account or will i be over and still have to buy Steam HeavensWard CE?

I don't want steam on my other PC and just want Purely FFXIV on it, Yes i know i can turn off but i'm letting my 14 year old kid brother play the games i don't.


So if you have info that the pre-order HeavensWard CE from Steam will have all the same perks and early access as the HeavensWard CE listed on SE website today or info on buying the NonSteam versions of the game will work for my account.

Thanks,
Jack
