So we're moving the goal post from "tri gear was good enough for everything" to "you didn't need tri gear"? Man, you must be fun at parties. No, dummy. You needed x amount of ap to grind at x. If you didn't have it and wanted to grind there, you needed friends. It doesn't change the fact that you still need the gear to solo it. There's still a need for it. Party grinding was bad, inefficient, and was only there as a crutch because nobody had the gear to do anything when they introduced content our servers weren't ready for. It's literally the same for Ash Forest right now. It's not a party designed spot, but because almost nobody has the gear to grind there, you have to party up to clear it at a decent pace. It'll be the same for Cave of Darkness.
