I'm a bit late but I was pretty frustrated with the battling too. I thought the first "lady" was frustrating but I was able to get 10 wins. The second one even more so, but I was also able to beat her. The satyr, though, caused me all kinds of frustration. I had some strategy going, and thought maybe I could get one win, but she was pulled while there were still 60+ left, so the minotaur could be released. (Ryan did say that he might ask to have some of the harder opponents re-released for a bit since they were so limited. There's a whole plot battle Q/A thread
here.)
I so do get everyone's frustration. My pet is ranked 25th, and was as high as 19th for a bit, and I still can't beat some of the opponents (though lower-statted pets with god weapons can do it easily). I've been training him nonstop for 5 years now but, because of people who can afford to boost their pets like crazy, he's still continually a step behind. Every time he gets close to beating Forj or Prodigy or something at that level, things are changed to make them harder again.
There is such a divide with battling on Subeta, and it's grown so much in even the past 2 years or so, that I'm not sure they could ever really fix it.
And, Rakumel, sorry to hear you had such a negative experience with BC chat. I do post there but often times don't know answers to questions, or wind up skipping a bunch of pages. Most people there really are pretty friendly in my experience, and there are a few that are really very helpful (they just "get" battling way more than I ever could).
