Screw Clank

Why does everyone make such a big deal out of him he already had enough popularity on R&C3 so i saw this coming if clank is going to be all that in R&C3 then obiviously in R&C4 Ratchet was going to be alot more popular.
beside Clank had very low health he was way to slow,and an banana gun?... please why is everyone complaining about this. Sure the story was short and very repetative but hey The online kicks ass.
