Janna is significantly better at defending a point because her self buffs aren't tied to her cc and is just as effective as lulu in a team fight and no she is not as tanky as a guy who can just heal himself over and over and has a stun with very good damage and a lower cooldown than polymorph.
Really the biggest problem with playing her that way is the length of her cooldowns wrecking her damage output and ability to buff/cc. You can't always be protected by a team fight playing her that way ruins her situational viability. I can totally trash champs like Xin and Ezeal one on one with my build and barely lose any effectiveness in a team fight and if you roam or defend a point with a single carry you are basically unstoppable unless they bring 4-5 champs.
