Make it together with flame system. They're both independent systems.
Nebulites have many benefits for us that flame cant replace although flame is stronger. Like the decent skill neb and abnormal time reduce neb, which my favorite.
Of course,some revamps of them shouldn't absent. Theres some of my suggest:
1) Remove all grade D nebs;
2) Release grade S nebs;
3) Adjust drop rate of neb box (lower cause removed grade D) or use nebulite fragment with a fair drop rate to replace neb box;
4) Revamp the skill of fusion nebs: remove fusion ticket and make the meso cost like star force. eg.1m meso if the higher one is C, 50mil if its B, 200m for A and 1bil for S (should add warning when fusing 2 nebs with different grade or having a chance of droping grade), even the star catching game for raising tier up chance can be add there;
5) Optimizing the nebulite stats. eg.remove all the accurency/avoid neb, etc.
