Long story made short: this tactic is soon to become obsolete because Firion was redone with a major overhaul in his moves for Duodecim. More precisely, his Fire>Shield Bash tactic is gonna be only a small part of his game.

Or people won't use it at all because it's boring and Duodecim is more balanced and Duodecim is ground orientated and stuff.....
It's not the feature of my strategy as it was in the first, but it's still a minor tactic I use occasionally. Rather useful when tactifully used.
