I would not comment it if there is no such post telling "do the boss, it is better".
In general, bosses have a bit better drops. That's true. No question asked.
But drops are not 2 times better. No point of fighting the boss if it cost 2 points… That's my opinion.
The only point of fighting the boss is if you know you not use all of your points – so you need to get rid of them before next day (points reset)
