No one wants a throne you've been sitting on!
What I would do for an Altenna or a Katarina mercy.
Also import OT might be delayed a few hours to a day since it's my first OT. Regular one should be fine and just be a basic copy paste when that's out.
You really should get it ready the day the game goes live. On the same day is fine, but generally a day late isnt not ideal.
Lots of OTs here at GAF to look at if you are wondering how to "format" your information. At least you mentioned you have the information ready to go, so should make things easier once you figure out how to format it for your OT.
