it with "it is." And if I look up "consider it is" in Cobuild English Dictionary, (I'm using an electronic dictionary so I can do this), I can find this whole phrase used in the result of "No doubt." I'll quote it: You use "no doubt" to indicate that you accept the truth of a particular point, but that you do not consider it is important or contradicts the rest of what you are saying. So, all in all, there must be some kind of grammar that I don't know. In fact, one of the natives said, "if you use it's, perhaps it's importance is proper." (She couldn't give me the reason. that's why I'm asking here) I have no idea why people changed "it's" to "it is." Semantically they are exactly the same. If one is "definitely wrong" then the other is too. Yes, writing was for a formal setting often follows the style that contractions are inappropriate. But "definitely wrong"? No. (I write all the time in various formal settings and use contractions frequently, so I'm not a good one to talk about that.) Rather than "We consider it is important to seek the best solution" I would suggest "We believe [that] it is important..."
