While the new Feature Guide system may be helpful to new players there are a couple of issues with the level requirements:
1) Supposedly you should be able to access the alliance Hero Academy at Sire level 23, however, this requires personal alliance contribution level 1. Unfortunately, you cannot access NPC Robert to break down gear to obtain donatable development items until level 25. This is not really logical or helpful. Might make more sense to have the level requirements for these switched.
2) Now that you can no longer access the Battlefield menu until level 50, there is nothing you can do with the Battlefield Medals obtained from Drakkari Slate Fragment combos except sell them for coins. It would be nice to still be able to donate them, even if you can't join Battlefield until level 50.
