I know this topic has been beaten to death lately, but I have this specific idea in mind and I fail to see how it is bad as some people claim. Someone convince me.
W!Eirika with bold fighter and miracle. She can charge miracle up on every initiation (or leave the counter at 1 if no counterattack occurs, which has the same result unless she gets oneshotted).
Of course this is mainly for a player controlled Eirika, where you can play smart and overextend only when it is safe. Add live to serve as sacred seal and she can heal back up after combat while properly supporting.
All of this while having flexible weapon, assist, A and C skill, so you can run a supportive set and refine for dazzling, or even go offensive with wrathful refine, atk solo or push and +atk nature. With bold fighter she can actually nuke some heroes in the process as she has super high attack, guaranteed doubles and targets res.
Anything I´m missing? Of course this is best utilized for multiple map modes/large maps/reinforcement GHBs etc... and has less application in arena or AR, but is a very flexible build nonetheless. Thoughts?
