They give a lot during events but they tend to get used up very quickly, also skills costs a fair bit to upgrade. If you want to do well during total assaults and stuff you want to focus your resources on certain units instead of trying to spread them out among everyone. Oh yeah and equipment is very important too, they eventually give percentage based stat increases.
