I'm sorry, but I fail to see what good a 13.3% end cost reduction is going to do when the effectiveness of my armors, attacks, and stamina have been decreased by around 33% from the enhancement nerfs.
As it was, I5 made my tank much more dependent on quickly dispatching enemies before they could dispatch me. Now, I'm going to have even further reduced defenses, meaning I need to arrest enemies even more quickly, but my attacks are weaker. So, I now have to spend more time, attacks, and endurance to arrest a villain, and my endurance recovery and defenses are nerfed to boot.
How does a 13.3% endurance cost buff help me again?
