Well, eight factions are enough for me, but if they add well-designed factions, I wouldn't mind. The game won't become less interesting. It will become boring if the factions are not well-designed and quickly become tiresome, and it's very difficult to create many interesting factions.
And at the same time, it's necessary to maintain balance and not go beyond the boundaries of the "Heroes" game world. Although it would be funny if they added cyberpunk to the 5th installment, just for laughs. Like mechs, for example.
