The Scimitar no longer works

Set reinforcement so it comes out first? I thought the order was decided by a preset priority, have I been mistaken this whole time?

As mentioned in another post, if they have r10 Darth Revan AND set reinforcements so that Scimitar comes out first, an r9 Leviathan is never winning the race to ultimate.  

What people have done in my fleet shard is set reinforcements so their Scimitar comes out first. If they have r10 DR and get their Scimitar out as first reinforcement, an r9 DR is never winning the ultimate race. 

This has nothing to do with delta... Ships get better stats from higher relics. Cap ships get more speed from relics.

It just takes one more lap to get through, but I haven't lost to it yet.  if you aren't doing the same process and just adding one more turn into it, you're changing what you're doing.  Bring out the scimitar when you normally would, even though it's after the sith fighter shows up, then destroy the hangar, then you should be fine.

The R10 gives more speed, but it's a waste of the R10 because you can still beat it.  And even R10 DR is still squishier than a gear 10 tank.

I could still win, but couldn’t win the ultimate race against r10 Leviathans. Had to play manually and hope Tie Defender didn’t dodge too many times. 

I’m in a crazy busy fleet shard so I just took DR to r10 to avoid this being an issue. 

Didn't once lose to r10 leviathan
only difference between between relic 9 when you start second and relic 10, enemy leviathan is able to call sith fighter without being destroyed, rest of the fight looks exactly the same

Have you tried your pilot with all 6* mods, added all omegas and zetas, or added your own higher relic pilot.
