Even with lower rates, leveling parties still won’t be a thing past 200 cause the power scaling is absolutely bonkers with the current trait system.
And we gotta remember that nowadays kRO has a lot of ways to just boost urself to 200, be it trough promotion or specific gears that makes 2nd/3rd classes extremely strong.
Not gonna spiral too much into it, but one of the main reasons party play went downhill is that Gravity refuses to understand one of its main systems is in dire need of a update— their looting system is still stuck in 2002. Even tho we have higher drop rates, "even share" isn’t actually even when you’re fighting your friends for loot. Since it’s all about one-shotting and speedrunning for efficiency now, having more people with you just messes up your ability to farm properly. We became an ARPG, without the ARPG main mechanics.
Imo the only reason we see parties for D1 and D2 is because the quest system exists, without the quests? Yeah, not a chance.
