buy ffxiv on se but want to play through steam?

[Risvertasashi]

i used too add it as an non steam game but it doesnt track time there when i look at my profile but if i just buy the arr on steam just for the client that it track the time and play there would it work for my heavensward too? so i still could buy the new dlc on square enix and all other stuff there too?

In theory, yes this would work. Buy the steam ARR just so you can launch the client, but keep using your old account. Do not try to buy expansions nor subscription time through steam. But I cannot guarantee this as I haven't done it myself. Steam does have the "less than 2 hours played refund" policy but that is also not a guarantee you will get a refund if it doesn't work out.

If you want a more certain answer, I would suggest going to the Square website's support and using their chat to get ahold of a representative and ask them directly.
