While I appreciate systems built to help players avoid making costly mistakes, this one is truly awful.

I would invite the developers to manually undergo the augmentation process for three capes and see how they feel about it then.

The menu is clunky and unresponsive, partly due to the NPC using emotes that lock us up. We have to trade two items each time, so we can't do it with a macro, and have to manually retarget each time. Fifty times. There must be some way to provide players with some level of protection without giving me repetitive strain injury at the same time. Add 2, 3, 4, 5, even 10 (!) confirmation steps to the full stack trade. Put the resulting augment in giant glowing orange text! Almost anything would be better.

I just traded my first set of 20 items and writing this post was a more appealing prospect than moving onto the second.
