once you pass level 70 it should take you 2 hours or so to do the dailly stuff, you can save SA to a weekend since its a weekly event or even do 1 try each day to reduce time.

worst part is really the timed events like plunder/convoy, 9tails and stuff like that.

Also if you work/study maybe play a bit during your brakes or lunch, 15-30 min here and there add up and save time when you get home because you will have stuff done already.
