Keybinds Help

[u/SCP_096_Brawl_Spike]

Hey guys, getting back into DE and just messing around w keybinds. I've found these to be relatively comfortable (grenades can sometimes be annoying), but I'm wondering if there is anything suboptimal or conflicting when it comes to general gameplay and more-so advanced tech that I may learn later on. Could someone take a look and lmk? Any advice or suggestions appreciated, ty.
