Okay, I understand now. I thought you were addressing my system, but I see you were referencing the BAB to damage idea.
Back to my system, I don't know how much horsepower it actually adds to the weapon-wielding characters. (Note: This rule applies to PCs and monsters who use weapons alike.) But that's because I haven't actually play-tested it yet. I may be doing so soon though as I am entertaining the idea of using it for my re-boot of Maure Castle PBP. The way I see it, monsters have a way to mitigate PCs getting three attacks at full BAB. Sometimes they will be able to use it, other times they won't, other times it won't even matter.
Example A: Monster takes a 5-foot step back and attacks. PC advances 5 feet as a swift action and makes two attacks at full bonus. In this situation compared to RAW a PC with a BAB of 6-10 is actually getting a nice little +5 bonus to his second attack. A PC with a BAB of 11-15 is getting the same bonus, but losing his third attack at -10, which probably doesn't hit very often, but still has a chance. A PC with a BAB of 16+ is getting the same bonus but losing two attacks, albiet both attacks that probably have a very poor chance of hitting. So at mid-levels I see this as a significant boost, possibly to the tune of 12.5% extra damage (I won't go into the math but it's relatively simple). At higher levels, maybe not so much. But it is difficult to tell at this point.
Example B: Monster is back against a wall or corner. PC gets all three attacks. In this case, it seems a significant boost at any BAB of 6+. I won't argue with you there. But then, a monster shouldn't want to ever have its back to a wall.
Example C: Monster is a Flyby-Attack type like a dragon. PCs don't often get to take on these types of monsters on their own terms. Getting in a full attack on such a monster doesn't seem to happen very often in my experience, and I've run a fair share of such encounters in 3.5, but maybe I'm just a mean DM who likes to use intelligent monster tactics.
Anyway, in cases like these, I don't think the change will have much of an effect. Although it might give PCs an improved chance of actually breaking that grapple check from the flyby improved grab.
Overall I would say it is a modest boost to high BAB classes. And I don't necessarily find that a bad thing. I don't think anyone would ever argue that the high BAB classes (aside from the warblade) are overpowered.
