I think is a total lack of respect for those who has maxed them out. Is a nice concept to be able to "upgrade" them to be at par with the new ones but there is no need to reset them all the way down. The only thing that changes on the progression of the new exotics is the use of materials (ascendant materials no longer needed), the XP requirements still in place. Each node upgrade is 25K XP witch at best is 5 bounties at worst is 13, so depending on your "dedication" it takes long time. The increase on attack is just about 20-30 points per attack so are you willing to go trough all those bounties for (up to 38) that little upgrade? why not just adding 2 or 3 nodes to the existing ones? the worst part could be that this will be an ongoing practice so they will do the same for any other DLCs, I know they want to keep us playing but give us content do not SLAVE us to the grind!
