So you're saying this arc will be pointless? There's a reason why the established boss of an arc gets defeated in the end of an arc. It's a reward and also it shows how the heroes grow.
I don't get why some don't think Doflamingo can be defeated.. Luffy has defeated relatively stronger enemies already. Remember Crocodile who was much stronger and nearly killed Luffy, Lucci who was several times stronger than Blueno who defeated Luffy easily their first encounter, Enel who one-hit basically all of the strawhats, even Buggy seemed impossible to defeat before we knew his weakness. Luffy always finds the weakness, yet people call him stupid, lol
