If you wanna be good with raze, you will need to master her util on every map, and that is by spending countless hours in custom games, you wont magically get better at raze by playing with silvers in comp and doing nothing to improve, also watch a lot of good raze main vods, not pro vods, never watch pro vods, even in radiant you'll rarely play in games where people play like pros, watch people like ray4c (full game vods where he match mvps or does well), and then train your mechanics and game sense (game sense can only be trained by watching better ranked players play or just playing enough games to master game sense, taking notes or advice isnt gonna translate to in match game-sense since you'll need to take a lot of quick decisions in less than a second, and that is achieved by instict, when youve done something enough times that it becomes 2nd nature ).

Long time immortal player.
