Rare enemy appearance rate

[MegamanX]

I know that you must complete the first 3 quests on the guild >_> .... I have... and i've completed all the forest quests I have after the 1st 3 quests... except Central Fire Dome thing... exremely hard for me (FOnewm pure-cast) >_> ... but what i'm saying... is it's acting as if I can only access Forest on standard game play (as in just starting a game and going to the Ragol Warp... no quests) On Ver.3 it was like that as well, if you only had Forest and Caves unlocked, you could only play the Forest and Cave quests at the guild... But for BB... if you haven't completed the appropriate Government quests to unlock your next areas, you can't play them... Yet my main account character completed all the quests, thus allowing my other 3 characters to play all areas as they please... yet I cannot exceed One Person Mode Forest Guild Quests? Can anyone explain? Or must I complete Central Dome Fire quest >_>, or what I dread more... having to complete all the Government Quests for each character to unlock all Solo Guild Quests?
