Ya there are many... many... ways to pull. You pretty much have to pick the right one for the situation in which you are in. A bard will truly excel at pulling when you get the Fading Memories AA. I change up my methods, as does everybody else, depending on the situation in which I am pulling. Bards in groups are pretty much known for their crazy pulling skills (and crazy train skills when they screw up).
Without Fading Memories AA:
When mobs are in the same area you can hit the surrounding mobs with your Lull song then throw, slow, debuff or DD the mob you wish to pull. If mobs are standing right next to each other and you really want the pull... you can mez or snare one in order to pull the other to your group. Just warn your group that another is inc. in a few seconds. Then mez the mob or have someone Crowd Control (CC) it. Always be aware of the mobs in the area you are pulling from and through. You also have to pay attention to respawning mobs.
With Fading Memories AA:
The only 2 abilities you have (under lvl 70) that cost mana is Charm and Fading Memories. When you first get FM you will probably not have a very large mana pool and mana regen on your armor and AA. Each time you use FM (instant cast AA) it uses 900 mana, if your finger happens to twitch as you press the button that's 1800 mana (lol). For the most part you will use FM to break an areas spawns up, so by the time of respawns, everything will be nice and easy single pulls. Mobs respond to line of site just like we do. Fade as one rounds a corner and then hit it again... he should come and all his friends will walk back. In an open area, pull a whole group of mobs, named included toward your group and circle short. Snare the named and pull all the rest back out of the way. Fade, tag the named and pull him into the group.
As I said.. there are many, many ways to pull. You will also die many, many times trying to perfect the skill. I have seen bards pull named mobs single from the back of instanced zones for Anguish Sigs. The better puller you are, the better people will remember you and invite you into groups. Nobody remembers the person that just sits in the back.
