who is "people" and what is "what we have now" ? cause "what we have now" is indeed in quite a sad state, but just go back to stormblood and it was in fact universally loved. stormblood bard was neither pure bard nor ranger and "people" loved it.
also what DO people really want ? you say bard/ranger split, but without meaning to offend you here, you are not "people", you have your own idea what you want and you say more people would want your idea instead of what we have but where is your prove for that ? the fact that we have a new split bard into bard/ranger thread every 4 days or so is hardly prove of anything unless you expect people that like the "idea" behind the current bard and are just unhappy with its performance (or even the factual selfishness/support split) to make threads saying "leave bard as is just please give us back foes requiem, but no no music otherwise please, because we know you want to do this but we actually like our archer/bard hybrid."
also what does bard mean to you personally? using music to attack ? buffing the group ? both of these ? also to what degree ? is dancer a good level of support/personal responsibility for this hypothetical bard or would this still be "not enough support, too much personal dps" ?
furthermore, who asked the general playerbase what they even honestly expect from splitting bard/ranger ? i mean sorry but the question what people expect from bard alone would probably give you people that say/want "more support" while actually meaning bard like it was during stormblood and another subset that says "pure music" which would than further get split between people that just want musical attacks and people that actually want more support and musical attacks at the same time. your own proposal of "musical attacks as a toggle" would probably not satisfy half the people that want a true bard if it meant gameplay would stay as is.
also what about ranger ? there are people that want ranger as a pet class or at least using animalistic abilitys, what about them ?these people completly aside, what even WOULD you turn a ranger into right now aside from a bard without any support ? cause that class i would imagine would hardly be beloved by anyone that currently plays bard, pretty sure that subset of players jumped onto machinist long ago.
