Changing Nations.

Scenerio: I am rank 10 Sandy, and I'm going to switch to Bastok. Now, I have friends that are Rank 8 Sandy. I want to help them still with the final BCNM.
Since I already completed that BCNM, would I still be able to enter even under Bastok? All I know is, once a person completes a mission BCNM, he/she can re-do it any time for another person; I'm just not sure if changing alliegences effects that. I looked all over, couldn't find an answer.

i believe once you've done the mission you can enter with sandy, asstok or windy doesnt matter

Yes you Can HAseyo... Im 10-10-10 all nations.. Yo ucan do it, as long as you completed the bcnm.

That's what I'm assuming. I can always just change back if not. Thanks!

Only certain missions; I believe missions like that (nation-specific) would be ok. However, if you are Rank 2 and your friend needs help with the 5-1 (which is the same for all nations) you would not be able to enter.

Kk, thanks all! :D

w00t Just finished Windy 10 last nite ^^

You can enter anything that you have completed before, there is one exception, and i think its the rank 5 like Alijah pointed out. It should say it on wiki.
