I'm not but they released the notes for the upcoming sandbox changes coming to swords. The perk that the eternitys edge has will become useless in this next update. The same for the titan exotic which mimics the perk on eternitys edge. I just want to know if they even have an idea what to do for it or if they remember if it exists.
On top of that why not change the swords archetype? After all, it's their game so they could just make something up and change it around so it's not just like every other legendary blade. (the exotic sword Worldline Zero also has the same perk)
So, if they keep it in the same archetype that perk is going to need some heavy changes to be considered at all. For example, all incoming damage is absorbed into the sword well blocking and the user will receive a locked number of damage every 5 seconds. The user can then use the heavy strike unleashingg all collected damage back into the target.
