The mage struggle couldn't be more real. Took my "mage" team into Elite Titan. Now I breeze through this with my main team listed below and 1-2 turn this with ease. Figured I'd try the mage squad to see how it works out......
Trance Terra -4100 hp, 906 mag, ring of lucii, Mateus Malice, Enhancer, 3 LA, dual wield, etc.
Zyrus - 4500 hp, ~800 mag, Mateus Malice, mag 30% etc. No dual wield.
Emperor - 4k hp, ~660 mag, Draco Spike, etc. No dual wield.
Aside from Magic Activation from TT and trying to spam dual cast alterna the damage was bad compared to Orlandu chains. Yes, I know chaining is broken, I have 3 of my own Orlandu but good god I didn't know magic damage was truly this bad without chaining. Dual TT or Enhanced TT change that, Enhanced Dark Fina changes this but we really need William and CG Sakura and the other mages to really mage an all mage team viable. TT is the finisher on my main team that is evade tank Noct, 2 Orlandu, Refia, and TT as the finisher using alterna. Easily puts out 12 million damage on Titan if I get my chains right. If you've watched JP you know mages are viable to a degree once we get good chaining mages. For now in GL unless you have dual TT using mag activation and chaos wave or dual dark fina with enhanced ultima, your mage is just better off being a finisher if you have ring of lucii.
***EDIT*** I could add DW to both Emp and Zyrus but I really don't know if it would have made that much of a difference at this point but it would have made a difference none the less. I'll try it again with all units using DW.
