Hi Mod Doom, thank you for the work you are doing, you’re awesome, we appreciate you continuing the line of communication with us.
Regarding the buffs system, if your intent is to keep the system, I think it would be interesting to have an in-game poll before each hero pass season asking the players to vote on their preferred buffs. This way the players are involved in the decision so there is less controversy, and you will in turn end up with the most popular buffs that should give you the most player engagement. As an ironman however, I would request continuing to keep the buffs disabled for iron accounts.
One buff I would always avoid is any kind of dps increase in pvm. Dps is king in this game and I could see such a buff creating some elitist attitudes (“Oh you don’t have the buff available? I won’t pvm with you then”).
