So our fix is to make sneak attack an action. This allows rogues to move and make a sneak attack in a single round. It does not allow a rogue with every TWF feat under the sun to take a half-dozen attacks and add 10d6 to every strike while using a full-round attack action.
Only a 19th leve rogue can add 10d6 on a sneak attack.
Theoretically, a 19th level rogue (BAB +14), with Ambidexterity, Two Weapon Fighting, Improved TWF, Combat Reflexes, Expert Tactician, Weapon Focus, Weapon Finesse, a 30 Dex, and two +5 Short Swords of Speed can make attacks of +30/+30/+30/+28/+28/+23/+23/+18. That's 8 attacks when making a full attack action against an opponent with no Dex modifier, or who he is flanking. That's potentially 88d6+40 damage (average of 348 damage, max of 568 damage) if all your attacks hit.
Unless of course that opponent happens to be a plant, ooze, undead, construct, has Uncanny Dodge, is under the effects of
obscuring mist,
blur,
displacement,
invisibility,
darkness, any other form of concealment, has
heavy Fortification on their armor, or is out of the reach of your weapons. All of which are quite common occurances at that level of play. Then (assuming you can reach your target) you only get 7 attacks with a full attack action, with a potential of 7d6+35 (average of 60 points) if all your attacks hit. If you can't do a full attack for some reason, it's only 2 attacks with a potential of 2d6+10 (average 17 damage). At 19th level, that's pitiful damage.
When sneak attack works, the rogue can be a demi-god of battle. When it doesn't/can't work, the rogue is a low-hit point, lightly armored fighter who doesn't do much damage.
