In today's patch the Gunblade changes were removed but they were:
** Hextech Gunblade**
* Renamed to "Capture Bolt"
* Notes it the active shares a cooldown with other Bolt items.
* Damage increased to 200 from 150.
Any reason into why changes to the item in the first place? Seems random, but it looks like they could be introducing new items with the same active, since there is currently no item that has an active named 'Capture Bolt'.
