In a future update we will be changing Hard Nodes back to 5 attempts per refresh. This was temporarily increased with the launch of Mods 2.0 to help players earn Jedi Knight Revan and Darth Revan.
Now that players have had a chance to earn these characters and players will have had much more time to unlock the prerequisite characters in future events, we will be returning back to 5 attempts per refresh.
We will also be reducing the Crystal price of Mod Salvage in shipments with the next update. This will still be a slightly more expensive way to obtain Mod Salvage compared to farming it from the nodes but a more convenient way to get those materials quickly.
