I find it hard not to vote for Higurashi given the success she has had with Aether. If it ain't broken, why fix it?
I completely agree that Higs has been an excellent master and there is really no overt reason for her to be replaced. Also, I do feel that all of the challengers, including myself, are more than qualified to be master of aether in the event that Higs loses the final battle.
However, I will provide a reason not to vote for Higs. In the times I've chatted with Higs since trials started, she has said more than once that she hopes to receive more of a challenge this trials. And if I were in her position, I would feel the same way because you should have to earn the title of master, not necessarily be given a significant advantage over your challenger that makes it easy to retain the title. While the voting this phase is technically for "who you think should be master", it is really more about who do you want to challenge higs, and how much of an advantage do you want to give Higs or the challenger.
Obviously, I am going to advocate for the community to vote for myself because I feel I can give Higs the challenge she is looking for. I gave higs an epic battle last war and I've beaten her recently in the finals of a tourney. I am not afraid nor intimidated of facing her, and I am very confident that I can push higs to her limits. My hope is that this will lead to a better performance in War #5 for team
, regardless of who the master is.
