I've played this game for 3 years, but have not improved at all: I still get myself killed in bot matches (which is the only thing I do regularly) and get completely destroyed in any casual / ranked game no matter what. A big problem I have is aiming, which is why I main Terminus. My accuracy with Androxus and Drogoz is 60-80%, but only because they are projectile characters. I now wish to main Lex, a hitscan character that most people think is cancer but is somehow a throwpick in ranked. Before anyone asks, I have played every character and prefer anything but supports because I'll have to constantly heal.

The following is my experience playing bot games. I'm under the impression that any game against real players is exponentially harder.

For me, aiming with this man is impossible! So I ask for small advice / tips on how aiming works.
Every game I play my accuracy is around 10%. Lex clearly looks like a hitscan champion, but his shots still do not seem to travel instantly. The second any enemy moves, I miss (my mouse sensitivity is 15 and FPS stays at 60).

With Death Hastens, my favorite talent, it's infuriating when his shots alternate from missing the right of the opponent's head to the left, with no opportunity for correction because I die instantly (when facing any character with 0 dps, you tend to die sooner than them). With Discovery (I see no practical use in Heroism), I can land 2-3 shots at a time before the reticle swells to the size of a hamburger, and landing 2 shots that deal 400 damage doesn't seem very helpful.

People accuse Lex of his spam, but doing so even at point blank range does not get me any damage / kills because 5 shots still don't hit anything. Because of this I have severe difficulty getting any kills or even damage. Maybe I'm just too bad. Help pls
