User blog comment:WOB Silas/Lulu -- strengths, weaknesses, and roles/@comment-3970297-20121018085952

Lulu is among the underrated supports [ At least when it comes to a champion that is 'pure' support ] and is actually one fo the most verstatile supports. Definitely not on par with Sona who is dubbed THE universal support, but there is almost no team composition that cannot benefit from having Lulu on the team.

Lulu's main strength is her ability to do everything. From my experiences, when I wanted to not play Sona, but still be a universal support champion, I played Orianna support. [ Despite what Oldmaneyebrows says, Orianna is a terrific support] because Orianna support can do everything. Unfortuantely, Lulu cannot do everything at the same time due to her skills having multiple purposes in one spell, suffering a lot of what Orianna does since Orianna support is limited based upon the Ball.

Lulu can overcome Sona and Taric, though the main reason why you cannot is because your playstyle of Lulu is not made to deal with it. TO overcome Sona and Taric, you have to change your playstyle of Lulu against them, and honestly, Lulu has the capability to do so, only limited by your own preferences. If you want, I could give you some pointers on how to play Lulu differently,
