Yes. Pro tip - Leave it to gather dust in your garage unless you play on a flat map like desert. Source - Time served Isida player who constantly ranked in first place. Your sanity will thank me for it :)

Not directed at kirby but it's funny when this happens. Due to the cone reduction a player several ranks below can kill an isida (especially one with a light hull) without using any great skill. Why should the onus of skill be on the isida player? If the change remains I feel my dear old isida will going into a looong hibernation :(

fire and freeze effects have a greater vertical cone than isida. the fire and freeze effects spread and you can target multiple enemies. isida cone change really is awful. i have used isida since i started playing and i am starting to hate it now :(
