I am no longer optimistic. The last time I paid to alpha/beta test a game and got long streaks of radio silence interrupted by infrequent, anemic patches I got Warcraft III Reforged.
I try to hold a fragment of hope, but I'm preparing for a dumpster fire (probably ignited by a barrelmancer).
Let the upcoming update speak for itself. Also keep in mind that Larian is still getting 3k-4k players a day so their feedback stream hasn't stopped even though I reckon most people here quit by now.
