To begin:
As of right now there has been a lot of discussion and/or complaints I've seen about the lack of content/lack of repeatable content. Ex: Dungeons, Raids, Trials, etc.
PvP
could be fun but right now there is not a lot of love going into making the genre as a whole enjoyable (God please give us RW roulette)
My Proposal:
The introduction of an instance similar to Deep Dungeons but leaning more heavily into an action oriented roguelike. Right now you might be thinking "Aren't Deep Dungeons roguelikes?" and you aren't wrong about that but in all honesty, PotD, HoH, and EO are (in my opinion) really boring and puts me to sleep.
Does that mean they're bad? Not necessarily, people enjoy it regardless of my opinion. But I find the fact that most of the mode involves avoiding enemies and pulling mobs one at a time in higher floors to be unengaging.
- Instead of Pomanders, I think equippable actions (like in Bozja) would give individual power rather than sharing a bag of them, most of which will end up never getting touched till the higher floors
- Character augments that you can pick up and stack on your character. Example: Augments that increase player speed, damage, health, defense, crit rate, crit damage, OGCD stacks, and decrease OGCD/GCD timers, etc.
- More diverse and experimental bosses and perhaps even bosses that appear within floors like normal enemies.
In addition to these: adding loot chests every few floors that can give you exclusive items as well as potsherds as extra incentive to play. Maybe achievements for reaching certain floors and the like. (And hopefully not a bunch of corridors for a map)
My hope is that this form of content will function so both casuals who want to experiment and hardcore players who want to optimize can both equally enjoy, both solo and in a party, that stays engaging long term. Along with that, should it have a good base, SE could simply add content to it rather than creating brand new content that is nearly copy-pasted as well as experimenting with new ideas.
