Did your LfB hit for 750k or so on average?
Without any skill buff and gear bonuses, I hit it like 800k to 1.1m on a small AOE. It is just pathetic. Bola ID give me around 600k - 800k without any hatred consumption and better AOE.
When in a situation where both LfB and Bola ID can hit, then LfB sucks anyways. But Bola ID can't insert itself into the middle of mobs for instant "on impact" damage. It also can't hit at random elevations like CA(all except Cluster Bombs) can.
Pretty much it's completely relegated to its very small situational windows. It's like a "cherry on top" attack atm, I think. Specialized clusters lol.
And, if it's only hitting for that amount of damage for you for 50 Hatred, it's just not worth it as the front runner. It needs to be 1 shotting the monsters it hits in the MPs, for that specific usage. Otherwise I think the other runes are the answer.
Dazzle good to use as much as possible to continuously stun. Maelstrom and Shooting Star have their own uses, like being caught sandwiched in walls. <- the impact won't go through the walls but the followups on those runes will.
Unfortunately that's all they're there for right now. Our Hatred generators are already the best in the game though, so I ain't even mad that Bola ID does more.
I'd rather them focus the attacks to have buffed utility, too. Instead of just damage. I'd be ok with something like LfB only doing like 800k-1.1m based on your weapon damage, if each time I hit the monsters with it it made them flinch or interrupted their attacks or something.
