I'd expect that the requirement for becoming a Ranker rather than just arriving at a certain floor is for them to pass the last test before that. The last test is probably something special and very competitive and not something where the fact that she could beat up some second floor Regulars counts for anything, while her combat capabilities are probably the last reason anyone would want a Guide on their team and it's not to say that it can't be expected that she's holding back as well.

Or maybe the Guide's road to becoming a Ranker is not for themselves to climb but to guide someone from the very beginning up to the top, choosing their 'Hero' or in FUG context 'God' and showing them their path.

Not that we have a reason to believe that Hwa Ryun is particularly interested in becoming a Ranker at this point, though.
