Play with your char. Warlock is a funny mastery, and bard are going to help you so much in pve (speed, noise, tambour; and dancing, mana orbit in party).
Or, if you prefer, you can delevel bard and take cleric. Cleric will give you more slots in partys at 90-100. If your choice but a char 75 ff to 80... tsss, dont start a new one
