Your expertise chart is outdated.
Thank you so much for the update. I'll see about updating it asap. If you know of an updated chart somewhere, that would be great. Thanks again!
EDIT: Actually, the chart isnt all that outdated, as it shows the basic foundation of how the tier system works. I'm not sure anyone has put together an updated chart yet and so the current chart will stay, however I will add a notation within the OP stating that some of the tier levels have been adjusted according.
