These are interesting to consider. Rock beats scissors beats paper beats rock, but two rocks beat two papers beat two scissors beat two rocks. That can take a moment to get your head around.
Is this a common or desirable PvP structure? PvP is frequently balanced as some form of rock-paper-scissors, and we often discuss whether it is balanced for group or solo play, but I have never heard discussion of interaction between the two. I have certainly seen it in PvE. A City of Heroes Scrapper solos much better than a Defender, but two Defenders can take out Archvillains handily.
Let’s phrase that differently: two support characters support each other but are very weak alone, while two strong solo builds do not gain much from playing alongside one another. Okay, we knew that one already. And then there’s my friend Adam, who makes dominating solo characters that excel in groups. Bastard.
