Don't be so quick to blame WoW itself for the reasoning you lag or run into fps issues. Just because people release addons or create WA strings doesn't mean they're flawless. I bet if you did a trial and error of loading WoW with 1 addon enabled each time you would find the culprit causing the issues. WA could very well be the offending addon due to once again, improper coding within WA strings.
