"Because the gravitational forces of a hollow sphere have alot to do with Starfleet battle tactics."
They have a lot to do with your attitude
Since YOU were the one who brought it up, I'm wondering if you are aware how ironic that statement is.
About the rotating modulation.
In 'best of both worlds' - the borg already adapted to the power systems frying modulation when Worf got past borg shields with his hand phaser set on DIFFERENT modulations.
Why exactly would a modulation that is effective against the ship's distribution nodes have any effect at all against drones? That's like saying you can knock out all of the Enterprise's computers just by setting your phasers on stun.
Also, you seem to forget about 'first contact' and 'voyager' in your posts
Not forgetting at all. I again repeat that the first use of weapons against the Borg did no damage at all in their first two encounters. I even SPECIFICALLY mentioned that this had ceased to be a factor by the next major encounter--namely First Contact--by which point Borg tactics had become so laughable as to render the entire point academic: you don't need deflector blasts to defeat later Borg ships, because all it takes to destroy one is a dozen properly aimed torpedoes and an overly elaborate time-travel adventure. By the time we get to Voyager, they're down to two phaser rifles and a hand grenade (and the survivors from the FC vessel fared little better in the 22nd century, it seems).
Had Voyager continued for another two seasons I have no doubt the entire Borg race would eventually be annihilated by Naomi Wildman's teddy bear.
And the fact that a new moduation/a new weapon ALWAYS got past borg shields on the first shots
You can keep saying it, and I'll keep debunking it, but I did just clearly illuminate not one but two separate instances where the first weapon strikes did no damage of any kind. And there's still Q-Who, where not one of four photon torpedoes fired at the cube did any damage at all.
is an obvious and large vulnerability of borg tech
After First Contact, yes. Prior to that--especially at Wolf-359--this was not the case. This appears not to be an actual weakness of Starfleet so much as a timely and effective fleetwide upgrade to Starfleet weapons some time in the early 2370s.
in 'best of both worlds' it was established that a deflector can provide a far more powerful discharge than all conventional weapons on the ship combined.
Yes, and IF you tune it to a frequency that is specifically effective against the Borg, it will do more damage than those weapons combined. If the weapons do no damage, then neither does the deflector.
You think exploiting this weakness doesn't "amount to a solid battle plan"

?
Only if the weakness you're attempting to exploit doesn't actually exist. The EVIDENCE suggests Starfleet's weapons were ineffective from the get go, and the only weapon they had--one that Enterprise discovered entirely by accident--was
immediately neutralized. Thus the only weakness left to exploit was the one Riker and Data used to ultimately destroy the ship: their hive mind interconnectedness. It was, finally, the only avenue that particular ship had not yet covered.
