I didn't know that Beamdog decided to include (or forgot to exclude) this fixpack since they said, that only the bugfixes would be implemented into P:T:EE. Needless to say when i first noticed it, i thought it was a bug.
I can understand why Qwinn decided to change the upgrade, since having the streaming blade (original), in some ways (powergaming ways) are kind of unfulfilling. However, if you look at it at a bigger perspective, the orignal idea (i presume) was to make three different blades, of which all of them had both pros and cons, which reflects the zerthimon philosophy (Balance in all things); and can be made in to a damage dealing weapon, defending weapon, or a mage weapon. Adding all those bonuses into one weapon, feels very, or actually extremely cheesy, and doesn't reflect the original idea about it at all.
Also, does this mean that the Kinstealer now has the lowest damage value, or does the streaming blade just take all good things, without adding any bads? Thinking about reporting this as a bug.
