Even the mobs that keep most of their spells are still generally trash.
And until we can unsummon like a Sadida can, we can't take on different roles without first taking time and effort to kill our summons directly- and the most common spells used by Osas buff the summons, or do minimal damage. So it's even harder than it seems at first. We have few ways to actually harm our summons.
TBH, Osa needs buffs. Most of the game is not 1v1 PvP. In the rest of the game, Summon Osas especially are a thorn in the side of strategic runs, their summons are loose cannons, and the Osamodas is super easy to burst down, unless it's built like an absolute insane tank (at which point, why bother playing an Osa at all? Just make a Feca or something).
