Remember where we are. We're in a thread tagged: Rogue.
Rapiers is the key here, as are shortswords, daggers, kukris, scimitars, etc. Any weapon weapon with a decent crit range and a x2 multiplier.
Rapiers are/were great for leveling, and then became all but useless in Epics with the atuo-crit scenarios that prevailed. With this change, the standard rogue weapon is no longer useless in epics. It is now just as effective as it ever was.
If you guys want to take this conversation into the Melee boards and complain that reduces options, I won't stop you. But here, in a rogue thread, it increases options.
