I'm not too surprised. ESOS is 14-20/x4 weapon with Holy Sword + Improved Critical feat plus basic Strikethrough; longsword is only 16-20/x4 with Knights Training feat, lower base damage and no Strikethrough. SWF longsword would be better DPS than S&B longsword: higher attack speed and higher damage modifier.
Your typical Vanguard will spec for bastard swords or dwarven axes to take advantage of:
- 1.6x damage modifier + Strikethrough bonuses from THF feats and Improved Second Strikes (KotC). Racial Strikethrough bonuses will stack too (e.g., Great Weapon Aptitude).
- +20% attack speed and shield-bashing bonuses from Vanguard tree.
- Helm paladins get bastard swords as favored weapons; but only the Forgotten Realms Iconics (excluding Morninglord) can worship him. Dwarves can make dwarven axes into favored weapons for 12 APs (Dwarven Axe Training III).
- Shield Mastery bonuses to doublestrike and PRR.
Don't need to tank? Respec into a THF DPS build just by resetting your Enhancements; then respec back into DPS-tank hybrid or full-tank when necessary.
The biggest downside is this is pretty feat-intensive and pure paladins don't get bonus feats. Fighter Vanguards get a lot more feats to play with, of course, but don't get paladin perks.
