I love this feature! :D I used it so much to train & evolve Pokemon when I was trying to complete my dex. I have the highest possible rank but it frustrates me how you can still run into lv. 15 trainers and etc when going through it.. they should weed those out the higher rank you obtain, but eh, I won't complain much. It's a great way to earn money and train. ;P
Same. When I go into the Chateau, I wanna fight Gym leaders and Elite 4 members and Audino girls, not some scrubs with level 15 Pokémon who're full of themselves. I'm Grand Duchess, gimme some real opponents.
Yeah it's kinda baffling that even in the higher ranks we can still end up fighting lower ranked Barons/Baronesses and Viscounts/Viscountesses. Well, at least there's still those writs that can raise levels of the trainers, but still yeah it kinda annoys me when I'm level grinding and I find myself battling mostly the weak ones.
And I get really infuriated by those ones who abuse Fake Out and Protect/Detect a lot, especially that one Countess who uses a Whirlipede, it's damn obsessed with using Protect. Also, a Viscount who uses a Mienfoo really likes to annoy as well since he likes opening with Fake Out and then use Detect next turn.
