Not exclusive, but bards definitly suffer from this the most. I have no
idea why all thse people assume they know how to play my 51 bard better than
I do. I guess they all play lvl 60 bards as their primaries. I still run
into to people that insist my normal haste songs (not the Ervaj ones) stack
haste effects with enchanters. "DEWD!!! I tested it MYSELF!!!!"

If I am in a group where I am lacking any realy good songs to play, I will
offer to play mana song full time. Usually this would involve having a
chanter/shaman and cleric (maybe 2 of the three along with another int
caster). It gives me a break from weaving, which is nice. However I
explain to them thsat they need to med close to the fights (thus must pull
close to the medders). USually they ignore me, so I go back to singing
other songs (since mana song ain't hitting the caters anyway).

When someone tells me what songs to play, I ignore the first time they say
it. Then say, "I know what I'm doing", the second time. If they continue,
it is dependent on my mood. I will usually just go back to ignoring them,
but occasionally I will go on a rant about how I don't tell them what
weapons to wield, skills to use, spells to cast, etc... It also depends on
their "tone" If they are trying to be helpful, I will merely explain whY i
am playing what songs I am singing. Occasionally someone actually makes a
good suggestion, and I will swtich my melody...
