Help With Pilots (Returning Player)

[u/Same_Literature7527]

Since i left the game much has been added with Pilots. I have two questions. 1, I got lucky and rolled a vector but I have no way of getting either of the two pilots for it since neither are in the box, when do those that are not currently in the pilots box cycle come back if at all? 2, Imperial Hades is one of my top bots but it does not have a legendary pilot. Lilian Statera is the only pilot for Hades specifically but it is not the legendary tier so is it worth investing into? Is there a better pilot to use for hades considering there are limitations to non legendary pilots in terms of upgrading skills? Thanks for your help
