I've had a cleric sub before, and I didn't like it. First of all, speed potions are extremely expensive, especially if you use them a lot. And if anyone is like me, I hate moving slow. It's annoying.
With bard, I have speed whenever I need it, and it saves me a bunch of money. I don't have to depend on scrolls or pots. Noise is one of the best skills anyone can have. I think you underestimate just how helpful this is for certain builds. With my wizard, I started with a cleric sub... Not only was it a SP drainer, I had a hard time staying alive because I'd get mobbed so easily. Once I curse hearted cleric and switched to bard, my survivability went way up and grinding became a lot quicker. Same with my rogue. I started with a cleric sub but grinding because a pain in the ass because I was getting mobbed and it was slow. I never used my cleric skills except for in pvp or when I was fighting a giant.
PVP is another story. Cleric, by far, is a better choice in PVP. But solo, bard is more helpful imo.
