Well some people do like them, but to each there own.
You only mention a handful for what it's worth, and even then not all were hits, alot were misses.
Yet despite this, they still got used in what their original owners professions were, more so with Aipom.
Not everyone was a fan of the trade either, especially since in the end, Dawn got shortchanged since Ambipom ended up leaving her.
I look back on this one as both a hit and a miss because while Gible was a nice addition and a first dragon to Ash, but the fact that they spammed Draco meteor so much made it feel to me like they only gave it to Ash to promote that attack, because there only a couple of times where Ash was not training it to use that move, i perfer pokemon to be abit more free than that when it comes to training, which is one of the reasons i don't mind the off-screen training that started with unova.
Look I like seeing characterization in pokemon too, but I also care more for seeing pokemon battle than anything else, because that is my personal preference to watching the show.
but that's what things boil down to, what you like watching the show for, and agree to disagree on things.
I wouldn't mind this, but i want them to evolve if they come back...meaing Rowlet needs to let go of the stone.
