Guys, I Have Jeffrey Questions

Okay so I hit plat 1 with Jeff, 1 week in so far, but guys I do have some Jeffrey questions please:

Everyone keeps talking about flanking jeff. Do I have to be super agro with him?

One GM Jeff said they only ever use ult offensively. Is this generally agreed? Sometimes I wanna use it to save my team like vs a Strange ult

How the hell do I position on the first 2 points of Royal Palace? (The ones where youre inside the palace)

What specifically does that Luna team-up do?

I love you my fellow Jeffreys. Lets keep the landsharks alive, one fight at a time! 👊
