If you play safe the boss is still a joke... you will pretty much die at this boss fight because you want to get this over with quickly so you end up over extending and getting hit by an enemy off screen.
I have a contrarian point of view on "playing it safe." If you play it safe or cheese a boss repeatedly, I don't see any need to fight them again on NG. You can make many bosses a joke. I did just that using the bowblade, including completely negating forms.
I use different methods and tactics against bosses per run. The last time I fought the failures it was NG+5. I used the Whirligig and a couple new tactics. First, I used the R2 charge to thwomp the melee versions, while managing the projectiles. Second, I used viscerals. The initial time I fought them I used my +10 BoM. I can wreck anything in BB with BoM and the NG+4 fight I did was no exception. I ran around to the weak links and carved them up in a few seconds. The fight
was a joke.
However, that doesn't mean that the boss is a solidified joke. You simply have the ability to make it work that way. Try using a straight up strategy and say they are easy. Now, there is some merit that strategy exploits are the way to go with BB because that is the design. Kind of like Mega Man's rock paper scissors. But I disagree. NG runs are designed for you to try different strategies, including using straight up skill. If you blow away a boss, the next time you should try to even the fight. And on NG+5, the living failures pack enough of a punch to post a challenge if you fight them in a non "safe" way.
All of these reasons is why I run low armor most of the time, limit item usage, and don't use lame weapons. Bosses are only a joke when they pose little threat if you remove the exploitation. BB does a pretty good job of not having too many of these.
PS: I don't like the living failures fight. But I play BB to get the most out of it.
PS2: Also just wanted to comment on all of the GOTY talk. BB is the best game I have played since 2008 when Valkyria Chronicles blew my mind. These supposed "games" with weak combat systems can go to the recycling bin.
