In case you want to listen instead of reading... (Destiny)
PCGamer posted an interview with some more Lightfall info.
I won’t break it all down this time, as I don’t have time right now, but there’s good info about new mods, changes, and loadouts. Resilience is being returned to provide a 30% resist instead of 40%, for example. All non-stat affecting mods will cost 1-3 energy. The new Font of Might equivalent will max at 22% increased damage with three copies of the mod, and you can select which element it works for rather than it having to match your subclass. Loadouts will be able to change the selectable perks on your guns.
Lots of neat details, go read!
Aztecross does a solid, quick breakdown with some thoughts on each point and what impact these changes bring.
