why the change with TWF?

[Roman]

Where is the fallacy of logic in that?

Let's see. Oh yes. When using a paralyzer, you are kept from using greensteel. Not Using greensteel = less DPS.

Again, you're using pure theory and half facts to derive metagaming implications. Don't do that. It's more than probable that standing still with greensteel will be far more effective than standing still with a paralyzer.

1 person sacrifices DPS on a single weapon to improve the DPS of 3-7+ other melee. Your argument is weak.
