^ You do realize that this is Grays first real fight since his battle with Mard Geer so how the hell has he not used any strategy in his last few fights? During his fights with Silver and Mard Geer he used plenty of strategy and the whole situation with Silver was to help Gray get over his trauma regarding Deliora and help him move on from it so I don't know what you mean when you say that his development with Silver was lacking. Regarding the End situation, you have to remember that no one knows the true story about End and who he is except Natsu and that everyone is still under the impression that End is the founder of Tartaros and that he is the strongest most vile demon from the book of Zeref so it makes sense that gray wants to kill End especially since it was his fathers dying wish.
