I tried bard, I was one mainly in 1.0 with being a WHM so I wanted to get the new story and try it out. The instant cast procs made it fun but I quickly got annoyed when I would have bloodletter reset twice while I was busy firing another WS due to the cast times. Personally like the story, and enjoyed what the new damage skills gave
I may go back to it, I never tried to focus on sks, but I did notice when an AST gave me a little buff my world changed for a few seconds and it wasn't so bad.
The mobility part I never really got. Even before 52, I didn't go running and jumping around. I found myself stationary a lot. Maybe this is in savage content? That I don't do. The instant casts though I did get annoyed with like I said, maybe if they allowed it to be used within the casting. Healing though I got to say it was nice not having a bard jump around all the time getting hit by things just to jump out of my range...that's a personal thing though.
Songs is another thing, we have TP recovery in a game that doesn't require it for about 80% of the content, same with MP. Sure there's some situations a mage that needs to raise a bunch, a overpower happy warrior or an aoe spamming dps. Otherwise, I liked Warden's, though I never used it except on a warriors berserk.
Maybe there's an even ground here? I get the use for WM, you sing a song to enhance your arrow, you stand and steady your aim. Though as an archer we should be skilled enough to walk and shoot. I've ran into a dead end..what could be done to make it so that when you stand still you sing your song / steady your aim and do extra damage but if you decide to move around a bunch you loose the dmg boost but gain the mobility. Yes, you'd have to take the DPS loss for moving and accept that but you can toggle as you go along. If not, that's as bad as those mages who ask for Cleric to go away, base it all on MND and want us to keep the dmg boost. Get something you need to have something else taken away.
