Maybe he was putting all of his energy into those attacks? Just because he isn't pulling out black holes doesn't necessarily mean he isn't using all of his raw Power Cosmic.Again with the increase in durability argument. Thor's durability did no increase.
It's no surprise. Thor's tanked far worse than the Silver Surfer's blasts. Far worse. Warlock's Gem blasts were useless against Thor due to his fortified immortal soul.
The sneak attack Drax pulled?

Bill did something incredibly similar.

I don't see any rise in durability. Hell, the Bill scene is even more impressive.
Bill was suffering from extreme injuries dealt to him by Thor. He was far from %100. And Bill isn't not Thor's equal in durability. That much has become obvious. He was still conscious by the way.
Once again, there was no rise in durability. I don't know where your getting this from.
He tanked simultaneous blows from Drax and Maxam unharmed. I just posted a scan of him doing something exactly similar, but instead of it being Maxam, it's the superior Hulk.
Thor tanking 4 consecutive shots to the head from Beta Ray Bill and only being downed moments after tanking a running swing from Beta Ray Bill to the back of the neck is a fair bit more impressive than anything he did in his first fight with the Infinity Watch in terms of durability. The only thing even worth noting for someone of Thor's level as impressive is him shrugging off a blow from Maxam and Drax, which is apparently nothing new if you saw the scans I posted.
Again, everything was consistent for the most part. Nothing is ever going to be exactly consistent however. Especially an arc crossing over 4 different titles. Look at Siege. We have the exact same seen shown in completely different ways at times.
On top of everything, Blood and Thunder is hardly the best Thor has done in terms of feats.
The Warrior Madness is when a god becomes filled with blood lust. Extreme emotion can force someone into it or one can enter it by clearing the mind and becoming a berserker. What Thor was suffering from was a result of the multiple incarnations created which damaged his mind, and caused him to grow more suspicious, until he created an imaginary person that was the madness inside of him personified.
The only thing similar between the two is that Thor runs around spinning his hammer like a maniac. In the true Warrior Madness, he however is still aware of his goals. In Blood and Thunder he was suspicious of everyone.
