I honestly don't think I ever understood or used the secret base stuff. I didn't have anyone local to play with, and I only had one game. I didn't know what it was for and I never really understood its concept. In Hoenn, the only place I made my secret base was in the bush to the west of Fortree City, because it was the closest one to a Pokemon Center. Had no idea what it was for, but I mostly used it like the Gen 2 bedroom where you could place down decorations and the like.
Like, I don't understand why people are excited about secret bases I guess. Yay a room I can decorate. Big woop? This was in the Sinnoh underground too and no one liked it then (when you could have traps etc to stop people getting in). What made the RSE ones so much better exactly? :|
Gen III wasn't really the best place to introduce something like this, because of the locality issue. Aside from my brother, I didn't have anyone local to play with either. The thing about Secret Bases now, is that the locality issue has been resolved, and there is a much higher incentive to personalize your room. We can finally, sort of, build our own gyms, although we will likely be played by the computer. I dunno, I always kind of looked at secret bases as the first instance of our character came to moving out and actually getting their own place, and that was the fun part for me. However, in my opinion, the idea of secret bases had long worn off by the time Sinnoh's secret bases came into effect, because they had the same locality issues, and I didn't like the Underground in general.
About the Blissey teams - I plan to build a mono-Healing Wish-Blissey team myself, but I'm a bit wary that Exp may not be given in these battles, because this seems like something that
TF GF may cut out. If they don't (hopefully!), then, assuming the pokemon is domestic, holding a lucky egg, and the highest Exp O-Power is active, and discounting Amie's boost, then a participant will net about 234.5 k experience for 'defeating' the whole team; this puts a freshly hatched egg between levels 57 and 65, which is high enough for the Battle Spot in most cases. Additionally, properly built (as in, pokemon providing three IVs apiece, and either low-leveled or self killing) EV teams fought with methods would net 84 EVs total, so about three iterations would be needed to max a stat out. Yay! If we could get groups of people to volunteer bases like this, then it would make pokemon rearing so much easier! This is, of course, assuming that Troll Freak doesn't Troll.
That kid on the right looks suspiciously like Max from the anime. Oh gawd.
Rather, Max's design was based on the Schoolboy Trainer Class, but I see what you mean. And given that there's a Schoolgirl, an Aroma Lady, a Rich Kid, a Lass, and a Schoolboy in the (Super) Secret Base, it looks like trainer customization has gone right back out the window...
