This thread will be long. I've highlighted the main points for those who want to skim.
To fix the exploit people were doing before update 1.18 they removed the bonus to sp from each individual mob, instead providing a bonus upon completion of a leve.
That's a step in the right direction but they need to have that bonus dependent on the difficulty of the leves themselves.
First: leve mobs need to no longer have weaker stats than non-leve mobs of similar ranks.
Fighting a mob in a leve should be just like fighting a mob of the same rank outside of a leve.
Second: Make the increases in difficulty correlate with party size again.
One star: Most mobs will not be in a party with other mobs and will be of a rank close to the suggested rank of the leve.
Two stars: Leve mobs will be a distribution of solo mobs and duo parties, and leve rank will be 3-5 ranks higher than the suggest leve rank.
3 stars: Leve mobs will be mostly duo parties with a few solo mobs and a few mob parties of 3, mob rank will be 6-9 ranks higher than the suggest leve rank.
4 stars: leve mobs will be mostly small parties of 3-4 with a few duo parties and a few parties small parties of 5-7. Mob ranks will be 10-12 ranks higher than the suggested leve rank.
5 stars: leve mobs will be small parties or large parties. Mob rank will be 13-15 ranks higher than the suggested leve rank.
Third: Repeal the set amount of mobs per leve, allowing mobs to keep spawning as long as there is time left AND have the Bonus sp upon completion be dependent on the amount of mobs killed AND the amount of sp gained from each mob.
Instead of giving a set amount of instanced mobs to kill in a set amount of time keep the time limit but have mobs continue to spawn as long as there is still time left in the leve.
And instead of having a base SP reward for the leve upon completion have that sp reward be dependent on the amount of mobs killed AND the amount of sp gained from killing them. Say 10-15% of all sp gained from all the mobs killed during the time limit.
For leves where you are hunting items that drop from leve mobs, give a lower bonus percentage from mob kills but then also provide a static bonus per item recovered.
For necrologos page hunts, have a certain number of pages still equate to a book that spawns harder mobs that provide more sp and also give a bigger percentage to the bonus at the end. But allow pages to still be gathered after each book mob is beaten.
This change alone will make each leve much more worthwhile, the 30 minute time limit will still allow it to be accessible for casual players. And the system will reward efficient, skillful playing. While also encouraging players to complete rank appropriate leves.
Fourth: Expand leves to include dungeon content, settlement defense, maybe even escort quests.
Now instead of just doing Thousand Maw for the boss drops, you can do thousand maw for SP, giving you goals beyond just getting to this chest and that boss... you now have to get this chest, get to that boss, and you need to kill so many pterocs, and for each pteroc you get a bonus upon completion. The bonus could even be awarded whether you successfully complete the dungeon or not. Making failures less severe.
Fifth: Change leves to a ticket system. 2 leve tickets a day up to a cap of 8.
It will be less leves overall but it will allow for people with different availability to have some flexibility. Not to mention that each leve will actually account for atleast half an hour of content, so each leve will take more time to complete and have more substantial rewards.
If you can only play on the weekends you have 6-8 leves at your disposal. If get a group for a dungeon instance this weekend you can do the instance and the appropriate leve for it.
---------
This would allow leves to be more centric to the game again, and would allow for more content centered around leves...
Leves would still be a casually accessible, while also allow for the more hardcore to enjoy them.
I have a further idea on changing how the sp cap works that would correlate well with my proposed change to leves... I'll write it up soon.
