Is it Good or Bad that Pacquiao has had 3 easy fights in a row?

Earlier in his career he was known as the fighter who went to war with his opponents. But ever since he started moving up in weight classes and changed to a more cautious style (which he has been very successful with), he has had three easy fights in a row lasting more than a year. I'm wondering if this is better, longetivity of his career, or worse, since he will be little unfamiliar when confronted with another war. I'd be worried about it if he were fighting nothing but chumps. His level of opposition has been good though and it's been more a case of him being so sharp too. I also think that's he's just so strong at 140. He doesn't have to drain himself anymore. I think that this is his optimal weight and that's why his results have been so good.
