Am I the only other person who finds champions that are pick or ban to be in an unhealthy state?

Anyone else agree?

Edit: Okay so now I'm going to add a bit of substance to my previous post as was requested by some of you.

Xin Zhao for example in my opinion is pick or ban. Basically if you don't pick or ban them, the enemy team gets them.. and you'd rather them not have that power in their hands. He has an insanely strong jungle clear due to even more sustain from his recent but un needed buff. Devourer in general is incredibly cost efficient and it promotes in my opinion once again an unhealthy play style of not helping your laners.. or if the game hits 20 minutes and you reach sated from power farming you can pull off unbelievable things like 1v3 because you have sated devourer and rageblade on xin zhao. I feel as though he just scales too darn well with attack speed now due to having his third strike crit and every other auto he heals. Another example I'll give, Tahm kench... even though he was recently nerfed I'm still seeing him banned relatively frequently.. as another summoner on the boards posted calling him "such an asstastic champion" I believe that's close that people still dont want him in their games and for good reason. What I see currently happening with balance as someone else had mentioned in this thread I believe that champions skill floors are getting lower allowing more people to take advantage of their strengths for example while someone playing a champ with a match higher skill floor stands no chance against him due to his now assassin like damage. I've also been reading about a kogmaw that builds tanky rage blade and that also sounds rather ridiculous. For awhile jax was pick or ban but it seems like people just aren't playing him as much anymore. I'll be happy to answer to anymore feed back, thanks guys =]
