one EIR advocate maintained that only TAFs and METARs were necessary to use the rating safely.
Oh well when little Tommy gets the all clear for Barcelona weather and then is expected to leave the airway before the STAR and happens to descend over the mountains bathed in thick cloud what use will his TAFS and Metars for Barcelona be to him

again little Tommy is struggling along on Top of solid! Departure weather great destination great! Enroute not so great! Infact the airports below are all reporting Overcast 200! Little Tommy has a problem! " oh dear I need to divert what do I do ? ".
Oh well
Pace
