Just gonna throw out a few suggestions, and let people do with them what they want.
Suggestion 1: Fixing new player retention
Problem: New players often find themselves alone or in very small numbers in comparison to the amount of 150's running around, and struggle to find groups for missions. This more than likely hurts retention
Fix: Implement an in-house system where a high level player can "mentor" low level players, which would result in them receiving meseta for each mission they do to help a low level player. This would make up for their profit loss for taking time out of their grind to help a lowbie. I know this would more than likely be hard to code into the game, so it would probably have to be an honor system ex: Run missions with low level, at the end, ask low level to clarify that he ran X missions to help, screenshot it, post it in a channel in discord called "Mentor screenshots" and then a mod or someone can pay them out the meseta at a later time or something, or maybe guardians cash. (i.e. 25 bonus guardians cash per mission or 50k meseta)
Suggestion 2: Cyclone Dance dmg output buff
Problem: Cyclone Dance feels god awful for the amount of PA frags + A blank disc that you spend on it. Spiral dance outclasses it on every level, especially since the just attack animation for double-saber is 100% garbage and noone wants to do it for cyclone dance
Solution: Increase damage output, or add a 2nd/3rd part to cyclone dance that extends the spinning animation, allowing us 2 chances to chain Just Attacks in to increase the damage output.
Suggestion 3: Rare drop problems (This is a very heated topic on discord almost daily, so it clearly needs to be addressed in some way)
Problem: SR/UR Drops are just too damn hard to find without committing 16+ hours a day to the game, and even then, it's still rough out here for most of us
Solution: Mission spotlights. Every weekend, spotlight a few missions and double their drop rates for the weekend (i.e. 1/2500 becomes 1/1250). Have it start Friday at 12pm EST, and end Sunday at 11:59pm EST. This will promote grouping, and also help lower levels group up to get the increased drops from the lower tier missions, which is a 2 birds 1 stone scenario. While this will put more rare items into the game and reduce their cost a bit, as the spotlight shifts each week, those items will find their way back to being "rare" again after the surge of drops loses attention for the next target.
