Tridon isn't even completely outclassed yet. I think there might be more, but off the top of my head I can only name Tridon and Gazia as units with flat 10% mitigation on their LS. Plus, Tridon is one of the few (if not the only) Barrier/Shield buffers that also offer HoT and BC/HC drops. That doesn't even include his DEF buff, which is currently only beaten by Mikael and Lugina by a measly 10%. Plus, Tridon is the only Shield buffer, so he's not even outclassed in that respect.

Also, Barrier buffs have no DEF at all, so they'll just get removed by a single hit, or just get torn apart. They're rather situational since their main point is to lower their respective element's damage to 1 (or was it the weak element? I don't remember too well).

I don't see why other GL exclusives lacking 7* evos would stop Gumi from releasing Dream Evos though. It hasn't stopped them from releasing Zeruiah, Randolph, or Ravenna.
