Except, like I mentioned, this "short-duration, but powerful" buffs thing was tried with vanilla WoW Paladins and people fucking hated it. Micromanaging buffs is even worse than micromanaging DoTs. At least with DoTs, you see a fairly tangible benefit to what you're doing. Buffs are entirely dependent on the skill, class, etc. of the person they are being given to.
Many people are clamoring forlessspastic gameplay in their MMOs, not more. It's one of the huge reasons cited for people playing FFXIV - it has an "oldschool" feel to it. Part of that oldschool feel is slower gameplay, longer GCDs, stuff like that. The EQ Bard is just more of the same spastic gameplay many people have grown tired of. It's a large part of all the flak levied at Wildstar. Sure, playing DDR for a boss encounter here and there is fine, even rewarding, at times. However, when literally every fight involves SC2 Diamond levels of APM? People get real sick of it, real quick.
