Reality actually alters the laws of existence as seen in Thor: Dark World.

The important thing to remember is that he has no emotional attachment to the Avengers. That’s why it was completely out of character when he broke his oath and sacrificed the Time Stone to save Stark’s life - that alone should have tipped most viewers off that he has an end game planned and he was playing Thanos. I highly expect we’ll see that in Infinity War 2.

He used the Time Stone prior to the battle. He knew what the only positive outcome was to beat Thanos. And giving Thanos the Stone right away not only would have given Thanos more time, but it would also make him doubt Doctor Strange. Strange had to distract him and make his actions believable otherwise Thanos would have probably realized he needed to use the Time Stone to see what Strange saw.

wow, I had totally forgotten that they implied the existence of Miles Morales in Homecoming, so this could be the perfect opportunity to bring him into the storyline. 

Lets talk about how Scarlett Witch is powerful enough to simultaneously destroy an infinity stone/kill Vision, and hold back Thanos (who has all the other stones)......yet needs Cap and Black Widow to save her ass earlier in the movie from a couple scrub black order goons. Legit

This is a good point.  Him surrendering the Stone to save Stark life is the big give away.  The less permanent death the better.  I was thinking about that part as well and thought it plugged some holes in Dr Strange decision.  Especially since Thanos specifically asked Dr Strange why he never used the stone as if he was ready for him to try.

In the comic she basically can bend reality around her and is probably on the same level as any of the most powerful mutants.  The other part about Wanda is that she is also very unstable and does not have not mastered her powers.  Emotions make her more power but even more unstable so it fits her formula.  Also its not like Thanos was in any great hurry to stop her since he know he could reverse what she was doing.

Ever since Civil War they have established that she is both unexperienced and scared to use her powers because she blames herself for the death of all of those people in the building that she blew up.  So I kind of understand her not going full on power on those guys in the middle of the city. 

Now, the scene with Thanos was totally different, there was absolutely no reason for her holding back.  On the contrary, she had all the reasons to let herself go all out. 

Oh ya....they really establish her to be inexperienced and scared by having Hawkeye show up and tell her to "get off her ass," which prompts her to pile drive Vision 50 yards or so underground (while manipulating his infinity stone) for no real reason. Why are they even together all of a sudden? Other than "because they get together in the comics." Matter of fact, why does the same romance subplot of "you have to kill me if it comes to it!" exist twice in this movie? When the pacing is already this hectic, and you got this much shit going on, wtf is the point?

I also don't buy the whole emotional instability of Wanda. If she can muster the strength she needs to kill Vision, who she supposedly loves, then she can muster the strength/adrenaline response necessary to defend him in the middle of the movie.

Keep in mind where her fuck up happened last time, she was in the middle of a crowded city area with lots of civilians around her, much like in Scotland where she first appeared with Vision, also... remember they were both just chilling out on a romantic get away, they were not expecting someone to drive a stake through Visions (previously God like) body. The second time she uses her powers she is on a battlefield, there are no civilians there, every person on the field is fighting and knows they are potentially risking their lives, also... she is not in "picnic with lover" mindset.

He might not have an emotional attachment to anyone else... but in 14million futures with deaths given out at random chances are Dr Strange saw his own demise close to 7 million times. Would be fucking tough to emotionally remove yourself from that.

@Lawlight, He turned Quills gun from being a weapon that would kill gamora into a bubble blowing toy... then turned that into bubbles as well, you have to imagine then that it could also alter the reality of what the time stone is capable of, wouldn't be very impressive if Dr. Strange played his trump card and all that came from his magic was a stream of bubbles at 88mph
