I'm honestly a bit surprised that the feedback I've gotten so far is that this change is a nerf. Let me explain why I called it a buff:
- Dagger type weapons are currently a standout as having the lowest comparative weapon winrate on Duelist by a fair margin, increasing the duration of invis that was granted had minimal impact on winrate.
- Way back in the early v2.0.0 alpha daggers used to have exactly this blink ability, I removed the blink and extended the invisibility before the beta as the overwhelming feedback I got was that the blink ability was absolutely busted.
If the ability does in fact still show as weak, there are a bunch of easy levers to turn now to make it stronger, such as increasing blink distance, invis duration, or having the ability occur instantly instead of spending 1 turn.
