So I'm not being paranoid
I'm bouncing in the ToF roughly between rank 50 and 120 (currently on my way down). The higher my rank, the more likely I will lose against almost every pushover comming my way - Kinkoid-'balancing' at work? As my ranking isn't that important to me, I don't care for tactics (I take on every fight and admittedly have won several, I didn't expect to), which wouldn't help anyway, as those losses are so highly improbable, that I had to cease fighting at all to avoid them. It's getting quite frustrating to watch opponents, who wouldn't normally pose any thread, score one crit after the other - honestly, I would prefer to lose more often against opponents who are actually stronger than me.
I've decided to use the arena merely as a training ground for the girls and forget about the ranking.
