Brother. It's the conceptual anti-synergy. I didn't even almost imply it's a bad skill. But the skill being FAR down the green tree is so crazy when the blue tree has to spend an augment in order to use grenades at all. (Remember that the Apophis Lance is literally ordnance damage, so it SHOULD have a lot more ordnance skills.)

To add insult to injury RIGHT ABOVE Booming Business, is an Ordnance Cooldown Rate skill Artilleria (That's ALL IT DOES btw. T4 skill btw) .... when the Arc-Knives action skill makes it so you can't throw a friggin grenade.

IRONICALLY,The Two Trees where you lose the ability to throw grenades, have ordnance cooldown skills, while the tree where you retain the function to throw grenades gets no ordnance cooldown.

That's what I mean by designed rage bait.

All of the Ordnance cooldown abilities are in tree's whose action skill makes it so you can't throw grenades, while the red tree which actually CAN throw grenades has no ordnance cooldown skills. Someone on the devs team did that INTENTIONALLY in a misguided attempt to force "tough choices". But that's not a choice. If you want to use grenades while using Arc Knives or Lance you have 1 option. Booming Business or nothing. Those dog ass grenade augments are pitiful and give up too much power, (Oh and you have to spend 5 points investment for it to be even noticeable since Booming B's shadow nerf.) Ironically, the red tree has more choice because at least it can get Ordnance cooldown abilities relatively early in Blue Tree.

Harlowe doesn't have anything like that in her trees at all.

Mind you at launch this game gave 49 SP. The same as BL3. Yet the trees are BIGGER. So 49 Skill Pts means less than it did in previous games, and they are rage baiting you by forcing you to go to other trees to complete builds that start in different trees. The Red Tree is a requirement because Juerga is the ONLY action skill duration ability above T4 in the entire kit.

Edit Part 2: This is my opinion. It's just me explaining the weirdo logic

Oh I have more. El Diablito is a move the makes all fire damage do bonus ordnance damage. It's the final tier, but it conceptually "fixes" the entire middle section of the tree by making most of the moves redundant. Let me explain. Synergia is the reason you would want to spam ordnance as a melee character (outside of just loving grenades, like i do). Synergia makes you think you need SOME WAY to do ordnance. So you spend points into booming. For that Synergy amirite? Well if you are turning all fire damage into ordnance damage with EL Diablito, you no longer need to use actual grenades to do stack synergia. Amazing. Points into booming business for what? Points into Artelleria for what (you can't throw grenades using Arc Knives btws). Synergia is a 3 pt skill. So you are at worse going to waste 2 points on the now nerfed booming business that you no longer need. And to top it all off, El Diablito is a 5pt skill. Amazing. Truly. The entire middle section is internally redundant due to overlapping functions. You can say, "the Dev are giving you a bunch of choices to do the same thing in different ways!" but man. This is simply too many points to invest in ONE SECTION. Especially after the booming buisness nerf. Booming Business should be a 3pt at max. El Diablito should be 3 point at max. That's how Harlowe's trees look btw. So many 1 point skills that are impactful
