Do we know when the next MTix will roughly be? If it's not too far away, I might wait it out until then to grab both tickets. If it'll take a while, I think I'll just grab Uriel now so that I get the benefit of a stronger team for the next few events. Then once the next MTix comes around, whether or not I get an SSR Light from gacha, I can start working on Light team since my Fire team would be set.
