Order 66 is not whale-only; learn the raid and stop whining

Having the new characters helps you get a better raid score. Yes, of course it does. That doesn't mean that only the new characters can be used in the raid. It's only been three days and already strategies have been figured out to put up a decent score even if you don't have Dark Side Clone, the new Bad Batch, or Jedi Master Mace Windu. 

Stop whining and git gud. 

There are at least 4 options accessible to mid-game and early-game rosters that will max score the lowest tier for 300k points.

Nest solo

Tarkin solo

Sana/Hondo

KBeq with some Jedi Vanguards

With these, you can put up a 1.2mln raid score with little difficulty. 50x1.2mln=60mln guild score. 60mln gets you the 5th reward box, which has max mk1 and mk2 tokens and 2000 mk3 raid tokens. 

But let's assume you have a tiny account, only 100 kyrotech to spare, and no patience for anything but the most easily and widely accessible characters. 

Tarkin: shards available in multiple stores, only needs 100 kyrotech to get to relic level, recommended modding is quite forgiving. He does need his two zetas. 

Tarkin will easily solo the first tier for 300k points. 50 x 300k = 15mln guild raid score, which gets you the 2nd reward box (max mk1 tokens, 8400 mk2 tokens, 1000 mk3 tokens). This is the absolute bare minimum, lowest-effort raid score that anyone can put up using a super old character that's widely accessible to any player. 

The strategy is simple: kill Fox first, use the event special, kill Appo, kill the other Clones, save the Jedi. Kill more Clones, save more Jedi. But you don't even need that strategy for Tarkin because he will destroy that first tier with ease if you put a few relic levels on him. If you can't be bothered to even do that, you are arguing in bad faith.

The raid is not exclusive to whales who have all the new characters. You just want to be angry.
