Replace player by character and you're basically there. Typical about MOBA's (and now also in e.g. Valorant these days) is that each character you choose comes with a certain 'kit' of skills and stats that give it different strength and weaknesses. A character might have powerful spells early on, others are very weak early but dominate towards the end because scale really well with extra resoures. The former will typically act in a more sacrificial role to enable the latter. The OpenAI favored a strategy where you snowball an early advantage into an early to midgame win, before the 'carry' characters start to dominate. That in itself is not new though, it just executed it in a weird but consistent way. One of the weird ways was indeed that 'egalitarian' way of having the 'support' characters be more greedy, enabling them to have a higher impact on the early/mid game timing, when the deathball starts rolling.
