I hate this scenario as well.
Much of the fun of theses games is experimenting & figuring things out. With the event tickets after so much has been invested, you don't have the freedom ta actually work on the puzzle & figure out your own solution.
You're not literally forced to use someone else's cookie-cutter guide, but all the incentives are to do exactly that. And the worst part is that as we scream for more content, just making the tickets unlock a single success rather than a single attempt **is** providing more content, because we get to play the event multiple times with different squads to see what the enemy is trying to do & figure out a way to counter it.
It would be a lovely event if we could actually spend time puzzling it & playing it, but the costs of doing so are far too high.
Ultimately I followed guides for Rey's t4-t6 (I did experiment on t1 since it was cheap & used that as a starting point for t2 & t3, which ended up working out fine) and even so I lost a total of 6 ultimate fights. Everyone else was saying it was easy, but I followed the mod strategy & the attack strategy & still lost. Obviously my experience is too limited to say that this was RNG or to know for sure if I was making some mistake in interpreting the guides or what, but it was so frustrating, so enraging, that I stopped farming tickets altogether.
Yes, I eventually finished my 10 x t6 victories, but not because I was trying to farm tickets. I stopped caring about the event altogether because it was too frustrating. I just farmed the toons I wanted to farm (BEFORE they changed the ticket drops to be based on energy) and tickets trickled in. If I won, I won, but I felt no joy, barely any relief. It was such a grind that getting an Ultimate Mat felt no better or worse to me than doing 5 sims on a hard-node character & getting a single shard to drop. It was like, "Okay, that's one part of a long farm, but no reason to get excited".
By not getting excited over victories, ultimately by not caring at all, I stopped being so disappointed in losses. But that didn't end my hatred for the format.
I have had my 10 ultimate mats for a long time now, but I haven't dropped them on Rey. I'm about 4 weeks out on the SLKR requirements, and I'm going to use those mats on SLKR instead. I'll still fight SLKR's t6, but this time I'll have the ultimate before I start, which will, presumably, make that tier much easier.
That's how much I hate this. I'm going 3 months without gearing an ultimate ability just so I never have to go through that frustration again.
As I've told many others: this is a game, and as such is supposed to be fun. If the most efficient path to power isn't fun, then take a different path.
I'm taking a different path, because your ticket system is the worst, CG.
I know you won't get rid of it, and moving the ticket drops to per-energy% was already a positive move, but it's still terrible. A move to tickets unlocking 1x rewards instead of 1x attempt would dramatically change it for the better.
Me, I'll probably still hate it based on past experience, but you could spare others my experience. You could make it a fun challenge rather than a mind numbing chore that people can't afford to do wrong, and thus can't afford not to repeat cookie-cutter battles handed down with step-by-step instructions.
Ending the ticket system, or at least causing tickets to unlock 1 victory rather than 1 attempt, doesn't just end frustration.
It literally adds playable content, since we're not playing this now, we're robots slavishly following someone else's recipe.
And it adds fun. Remember fun?
Using GLs is fun & necessary, but there's nothing about getting them that's fun. Why not change that?
