I also wish to see some updates and improvements on SR4, like, as I said on FB, adjusting dice pools according to wounds and spells, the "customize" button not being greyed when you buy a vehicule or a drone, and so on.
SR4 is prefered over SR5 by most of the DMs, due to the abondant available resources, books and internet.
It's like HL is mostly rolling for Paizo and Pathfinder
