I guess you're kind of right about having a carrot for paying players by giving a few exclusives. I'd prefer it if their prices weren't so steep, though. Would be more inclined to spend some if the prices got a bit lower. Not saying they should lower them by loads, but as an example i paid 50$ recently to get 70 SCs in aigis, and that's 14 spins at the wheel of fortune so to say.
Can agree with adding ways that are not fully RNG, that'd probably make it easier, for me at least, to justify the price.

That said, i will probably cave in near the end of the event and get a few event tickets. Trying to save up reveal cards for that moment.
