Since simple complaining rarely works, I'll try something else - making some specific suggestions. Here are some changes in the bard trees I think would make them better.
The most important thing to not make bards totally useless in ddo is to make all the effects from bardsongs that affect party members damage, saves, skills, doublestrike, prr, spellpower, etc STACK with everything else in the game. They need to be unique bonuses that can be acquired in NO WAY besides having a bard in the party. This should include all bard abilities, including warchanter capstone.
Also Have spellsinger grant 1 spellpower to positive and (ughh) sonic spells, and have warchanter grant 0.75 to same. For each point spent in the tree.
For spellsinger tree:
Return the percent chance of regening spellpoints to party members based on perform skill as a core ability, perhaps by adding it to the virtuoso core ability. But find somewhere, and add it. This is the most important thing. I cannot stress this enough.
Change Flicker and inspire flicker to auto-proc a diplomacy effect with a +20 bonus when it makes you invisible. Do not make Flicker or inspired flicker a prerequisite for anything else, other than each other.
Have marigold crown grant +1 to all spell DCs.
Eliminate reviving verse, put three tiers of bard spell penetration here instead with no prerequisite.
Where bard spell penetration is, put “adds ice storm to your spell book”. Bards should always have had ice storm anyway.
Eliminate raucous refrain, have a song that grants +10/20/30 stacking universal spellpower to allies here instead make that, and only that a prerequisite for arcane aid, which should be the same song as the spellpower song rather than inspire competence.
Change song of capering to an aoe effect so it has value rather than being a poor substitute for ottos irresistible dance.
Change frolic so it works as freedom of movement used to (correctly)_ work- and grant immunity to everything that impedes movement, whether it is a magical, nonmagical, or special effect (including everything). Make it only 1 minute instead of three, and affected by bard song length modifiers. Otherwise eliminate it entirely and add some other song to bard spellbook in this place, maybe reconstruct, prismatic spray, mass hold monster, or body of the sun.
Change the spellsinger capstone so that instead of granting wail of the banshee it grants either “wall of sound” if you can get to adding that, or energy drain. Bards are not going to get high enough DCs to make wail viable beyond maybe normal difficulty quests against mobs with low saves. Energy drain could actually benefit the party a bit, wall of sound would actually be pretty cool. Also give the spellsinger capstone +4 chr instead of 2 and +20 spellpower instead of 10 to make it competitive with the warchanter one.
Make skaldic rage stack with all other types of rage and/or extend its duration to double the current duration.
Make inspired bravery cost 2 points per tier and also grant +1 stacking damage to inspire courage.
Make victory song last 2 minutes instead of 20 seconds. Skip the vorpal thing extending it.
Since it is probably pointless to say “eliminate Gathering Cold and everything associated with it”, let me suggest the following changes:
Make armor of frost grant 5/10/15% cold resist rather than stacking +1/2/3 cold resist rather than 12 seconds.
Eliminate the -5 attack penalty associated with howl of the north. This is a tier 5 ability!
Make Ironskin chant grant +5/10/15 stacking prr instead of dr. or make it 3/6/9 dr
