New meta

If it required Jedi Luke and several new characters, it would be reasonably hard to get, especially for newer players.

Jedi Luke's requirements were designed to be very difficult for new players, but not nearly as difficult for older ones.

Why? Well, the r3 requirement is not much worse than what was required for GA$ - it's about the same number of toons, but requiring all to be relic'd is harder, while the fact that in the GA$ event some needed to be significantly above r3 for success, using up more precious signal data and higher relic pieces. It's a little worse, since you could keep your GA$ relic characters down at r3 or so if you were willing to try many times, and JKL has a hard minimum of r3 for every character, but JKL is also (so I'm told) easy to complete at that r3 level where many people had trouble with GA$ even after meeting the minimums.

BUT two of the characters are GET1 toons (HY exclusively, and Wampa almost exclusively since you otherwise have to have a very good bounty hunter team - at least very good by new player standards - and even then only collect 20 shards every 7 weeks to 2 months, at best it's 14 shards/month or 2 years to farm exclusively by Galactic Bounties).

New players find GET1 difficult to acquire in any quantity, but old players generally have Wampa & HY at 7* already.

Thus any requirement for Jedi Luke to get a further character would likewise be extremely difficult and/or expensive for newer players (I'm assuming you can buy HY and Wampa shards for crystals in Shipments but I haven't actually checked).

This is a great bit of game balance, if you ask me. It doesn't give anything away, but at release the biggest barrier was shards of difficult-to-access toons (gearing 9 characters to r3 doesn't take 2 years) which was already met by the old-timers.

I think there is a very important place in the game for krakens & whales - they literally pay for the rest of us to be able to plays this game. So I don't want to hurt them or discourage them, but that doesn't mean that every character should be for easy sale.

So I'd strongly support using Jedi Luke as a prerequisite for a newer Jedi Master Luke character down the road. That said, I think it's too soon to introduce Jedi Master Luke. Jedi Luke's event should be available to play 24/7/365 in the Journey Guide before that happens.
