I get that you don't like it and that you won't capture one to use, but to label it as "the lamest Pokémon in existence" is more of just your own opinion. I myself am not a fan, yet I still don't degrade it because of that. Also, maybe because it's pre-evolution isn't all too great in stats is why it's getting an evolution. It's called improvement and it may not be your style of things, but I'm sure it is to others. u_uI'm not getting one, since Luvdisc is the lamest Pokemon in existence, so why in the bloody hell would they make an evolution to one of the most hated Pokemon, probably just to torture us.....
Since the region doesn't look like there's too many water-filled areas, my guess is this region won't have as much Water Type Pokémon. It probably explains why we haven't seen that many Water Types revealed either. It's time GameFreak focuses more on the other types for a change; like that Rock Pokémon for instance, which by the way I find is pretty cool.
