It's so bad it's not even funny.
We had the 3.5 rule about bows and ammo as a house rule long before 3.5. We started with the old rule. I played an elf archer cleric (I knew it would be a very powerful concept, and that was intentional - to get rid of the old 2e walking bandaid image clerics still had in our campaign. It was still dumped on the new guy cause everyone else didn't want to be good for nothing but healing).
I give you that I started him on relatively high level. The other character went home (it was originally a ravenloft campaign, most had FR characters who were sucked in, I opted for a Rokugani one. When the DM decided to put them back out of Ravenloft, my Ninja of course went home, not to the Realms) and I dropped that archer in there.
He'd cast three extended greater magic weapons each day - one on his bow, and two on a stack of 50 arrows each. With a magical composite bow that adapted to the wearer's strength, 3.0 divine favour, 3.0 divine power, 3.0 righteous might, +4 arrows in a +4 bow, combined with boots of speed and rapid shot, I later got in 6 attacks (4 for BAB, 1 for speed, 1 for rapid shot), with something like
BAB 16/16/11/6/1
Dex +7
DF +5
Size -1
RS -2
Bow +4
Ammo +4
-> 34/34/34/29/24/19
At 2d6 (large bow)
+ Str +6
+ DF +5
+ Bw +4
+ Ar +4
+ Energy +1d6
for 2d6 +19 (+1d6).
Not counting Point-Blank shot.
I could use all the attacks most of the time (no need to follow enemies), and with persistant/quicken, I'd have most buffs on, especially in the big fights.
The DM then approached me to say something about the arrows. Since I didn't like how you had to have magical arrows to overcome DR, I gladly suggested them not to stack, but letting the bow transfer its power to the arrows.
We also quickly took away persistant spell (for quicken spell).
People were complaining that the character was rocking so hard. Mission accomplished, that was the last game where people would avoid clerics like the plague.
