I'm pointing out how he had to rely way more on his smarts than his powers which he hasn't fully grasped yet because he was still in training during the entire film. His smarts is was and always will be his synonymous with the character. At that time, as a rookie who is still taking baby steps, it's the only option he had. When he becomes sorcerer supreme he will hopefully have a rich arsenal of powers and hopefully they won't nerf him too much (considering what Feige said about Captain Marvel being the strongest character in the MCU i'm afraid they will). The entire film all Strange could do was repeat the same 2 feats summoning the same portal and a magic whip he created that's it. Even his martial arts looked very bad. Strange is not only a master of the mystic but also the martial arts. I hope this was done deliberately to show his gradual growth as a sorcerer and he achieves many many more skills along the way in his sequel etc. I know they will nerf him compared to classic Strange as he was waaaaay too OP but he shouldn't be less powerful than Captain Marvel and the powers Strange has in this film is like 0.1% of his feats in the comics.
