I recently got the WiFi Connection running but until now I haven't tried a battle..It's just a little bit hard to find 6 Pokes that can team up and then ev train them..I don't want a everyones-standard-team so I try using faves..I just can't end the ev-training with all of them..
I play both sides of the spectrum, I keep competitive teams (not very good ones) and my old favorites. I enjoy battling online, but the Game itself still has meaning to me, and I still feel an attachment to my pokemon. I'd lean more at casual, citing my inexperience in the competitive world.
im extremely casual, due to the fact that if i was competitive, ID SUCK!!!! i dont have the patience to breed for natures or EV train. which is why id never post a rate my team, cause if someone were to suggest a different nature, id go crazy telling them i dont have that kind of patience. nearly all my movesets repeat a type, and i dont have one designated HM slave: my main team all know HMs so i fight with a pokemon knowing rock smash. the point is, im way too bad to be competitive.
I'm basically a casual Pokemon gamer. I like EV training (in most cases) during the game and to battle friends, but I must admit I prefer using my favorites more than simply going full-bore into being competitive
I'm somewhere in between. I've recently started EV Training but I still use my favourites. Right now I'm working on a Golduck team. I bred seven Psyduck, and only one was a reject. ;054; So I'm not so competetive that I'll only use the "best" Pokémon. I also grow very attached to them, and even my reject gets love. I also have a lot of fun playing Online.
I'm mostly casual. I EV some of the time and sometimes breed enough to get the right nature, but I never do anything for IVs. Additionally, I very rarely have any semblence of a rounded team. I don't use many walls or bulky Pokmeon and mainly make teams of sweepers with somewhat balanced types.
