To start, I wanna say that I'm extremely happy with how things have been going with ToT and, more specifically, the cap that was implemented for ranked point gains/losses. That said, I do think the system could use a bit more minor tweaking just in the calculations for how much one gains for a win.
The impetus for this post is that I just played the same person in ranked three times in a row and had a net loss of 54 points despite winning 2/3 of our games. While I don't necessarily think I should have gotten +150 for both of the wins, the two wins combined should at a very least supersede the single loss. Something like a net gain of 40-50 seems more reasonable to me for winning 2/3 games against the same opponent when (relatively) evenly matched.
