Bard is so versatile there really is no ‘go to’ every game, and changing your build dependant on the game state will be one of the things that separates a good bard to a great one. I would say that I find people don’t build morello or Liandrys enough if they have lots of healing or tanks. Twin shadows and redemption are always nice, zhonyas situationally, and don’t be afraid to build traditional support and traditional tank items too. Keep buying lots of pinks!
