Agree 100% with the OP here. Too many times I have joined pickup groups with a mage that doesn't have all proc spells. Worst example was a Tablilla group where the whm didn't have Banish III, Flash and Banishga II. To top it off, he didn't have a single flux in Altepa and he was subbing brd to ballad himself... I asked him to try Dark Threnody several times but got ignored (probably didn't even have that :/ ). Also way too many blms are missing some AM spells.
