I have a band and we actively play local shows with out own music. The other day the drummer approached me and told me that i needed to change how i was playing. he said that I follow the guitar players too much and that I should follow more rhythm and change away form what the guitar players are playing.
Now I play in a Alt-rock indie band and I mostly just play the root note and the occasional riffs in the songs. Any advice as to what I should do? what area of music should I try to learn to make real good basslines given a song structure/progression? 

, but yeah everyone else have given me great advice that I will take strongly when Im at practice next time
