Tsk, and I still think that Julia without her field effect was way harder than current Julia. At least before, there was no way to avoid the explosions. That was annoying.
To be completely honest, I can agree with one thing: Grinding for Julia is a pain in the ass. Yes, unless you already know what to do against her (Bring a Kricketune/Cheap it with Goldeen), you're kinda screwed. It is my complain for the starting area of the game: No reliable way to level your pokémons, in case you wanna try something else. You just deal with it.
Now, I'd love to go through some of your points, but last time I did something like that, there was really no point. So, all I'll say right now is that, apart from the grinding thing, it seems to me that you're giving up on the first wall you've met in Reborn.
But that's just me.
