Misnomers and mismatched stats are a known issue, due to strange localizations and wording with the various stats. If, however, an item has completely incorrect stat names on the item description compared to the REAL stat it gives, you can take screenshots of the before/after stat C-page as well as a screenshot of the item description itself and send an RT or make a post on the bug subforum (although localization errors are not top of the priority scale, it is good to know what needs to be fixed regardless).
The FPS issue is also a known issue and we can expect a main patch to fix it within 1-2 months if the developers' plans do not change.
