What purpose do the different infusion types serve? Because apart from being needlessly complex, the option to fill defensive slots with offensive infusions is still there (just costs more to make). Furthermore, ArenaNet forces itself to make each item 3 times, which seems like a waste of time to me.
Why not all merge them to 1 type? I don’t think anyone would complain if certain infusions could ‘only be applied to amulets’. If anything, it’s more clear than the system we have now.
If you can read this then it is proof that ArenaNet’s moderators just, kind and fair.
