I was wondering about something - If you're equipped with a endgaming level weapon and enter a lower level (pre lv50) dungeon or fate battle, would the same damage inflicted be taken into account, just like in any area of the game, outside of dungeons/fates?

e.g. using a lv50 sword (or bow/arrows), and similar level gear, in a dungeon such as Sastasha at Lv17.

I already know that your level will be synced, as well as the abilities that are available, prior to the synced level.

What about post lv50 weaponry/gear when Heavensward is out?
