This is a bit of why I'm a tad bit hesitant on using MTix for Light, at least this current ticket. I already have 100% Eido+4SSR for my Dark team. I doubt Raphael+SSRarty+SR and either Michael or Tish would be up to par compared to my Dark team: Satan+Pluto+Chernobog+Amon Unleashed(which I'm currently using Kali until they make Amon's def down a C frame).
My Fire team which does NOT have an 100% Eido(currently using MLB Adramelech) is already doing more damage than my Dark VS non-elemental weakness. Only issue is, my staple fire team currently only consists of Amaterasu, Ares, Mars, and Heph as a filler. I do have backup SSRs for different situations: Prometheus, Yamaraja, Dakki, EOH Beelzebub. Oddly enough, my Water team too does not have an 100% Eido but is using Monoceros that I got from the event last month. Surprisingly, its able to push out roughly the same damage as my Dark team. Fortunately, my water team does not need a MTix: Asherah/Cthulhu/Nike(unleashed)/Ryu-Oh.
I'm tempted to go Light only because of all the comments I've read about how Light will only become meta and OP from this point on. But at the same time, I feel like grabbing Uriel to replace Heph for my fire team would give me one really strong team for farming. Not only that, since my Fire weapon grid is also the best of the 3 elements, I can spend more resources upgrading my Dark weapon sklvls as well as slowly replace my water grid with more assaults. Then once I'm lucky enough to get a Light SSR or two(strong ones) before the next MTix, well my Fire/Water/Dark already doesn't need the MTix anymore, and that would allow me to use MTix on Light for a 4 SSR team.
Of course I may be wrong thinking that Raphael+SSRarty+SR+ Michael or Tish is weaker due to being 3SSRs and Raphael not being the best light SSR. But yeah, after taking the above situations into consideration, would it be best to postpone thinking about Light and focus on getting my current strongest team(fire) even stronger so I can farm events+contribute more to UEs. Then once I get some "core" Light SSR, Light becomes #1 Priority for next MTix. OR, am I wrong in my thinking and using the MTix now would make my Light the strongest team of all my elements, including compared to my fire team even after grabbing Uriel.
Edit: After re-reading, I'm not sure if its just me or if somehow I sound very condescending. No clue how to change things to sound better as well, so I'm gonna just say it here that I don't mean to in anyway be rude.
