How to get other raids?

For the episode quest you just need to do the attempt, you don’t need to submit.  A forfeit will count.

I know this is solved by crazydroid's answer, but I'd like to point out you do have solid teams that can solo Order 66 raid.  Tarkin is a solid performer and easy to get.  He's also a solid fleet commander for early game, so you can't go wrong putting a relic on him.  Another easy farm is Nest.  She can solo the raid as well.  That's 600k points right there if you do level zero at relic 3 for each of those toons.  More if you take them to R7 and do level 1 or 2.  Hondo the grey can solo the raid, just needs his zetas.  Other teams to work on which make solid performances, you just got some Jedi to free relic level.  Beq, Secura, Shaak Ti, Plo Kloon and Qui-Gon will put a large dent in the raid and are again easy farms with the free tokens we just got as well as quick leveling with tokens from the era store coliseum wins.  1000 tokens gets you a g12 toon and 5000 gets you an Relic toon.  So you do have a way to contribute to your guild.  Never undersell what you offer your team.  Be thankful your team mates are carrying you in the raid that gives good reward tokens so you can accelerate your teams faster. 

I've added two screen grabs from Geist Knight.  Make sure you mod speed secondary's on every mod.  You want to be very fast to take out Fox and Appo first.  You got this.

I took a month off to let the new content settle and the bugs to be sorted; on returning I want to try some of the old stuff.  TBs isn't much of an issue, you can find guilds to do that.  However, raids was a real toothache.  I'd love to see if I could solo Tank or Sith raids, but finding a guild doing them, waiting long enough to be eligible and then being able to get some attempts in............was a real pain.....I got one speeder bike run (which I wasn't interested in anyway).    Anyway, I'm a little off path.  My point is leaving and joining other guilds to do raids and then going back to your original guild.............is definitely not an option.  

Well, I could get to 460k (2 battles) in order 66 with 3 Jedi including with Ayala at relic 5 accompanied by no-relic 7 star Tarkin & Quigon, that’s as far as I could get :) Thanks for pointing out that Tarkin can solo it, will up him as much аs I can. Or, in a meanwhile I can still try changing the guild at least to check out other raids for which I have way more relic’ed characters than 3 Jedi… while getting both Tarkin and Quigon to relics.

Tarkin at R7 can solo the 450k tier, I have hondo at R3 no zetas i use Ithano lead thats another 300k, then i use KB,Plo,Aayla,Shaak quigon for 900k could possibly do the next tier up, then left over jedi for another 2 runs, all up I average about 2.2m score, the old raids don't offer anything any more the only guilds doing them are ones that can't hit first crate in Order 66 you would be getting less value for a bigger score
