1. Aimbots for legions do NOT exist.
2. The max damage the LR can do on an outrider is ~53% (someone correct me if I'm wrong)
3. The LR requires quite a bit of skill.
4. People need to learn how to dodge - if you fly in a predictable path, you ought to be sniped. When I take the flag, I juke a little bit to one side to avoid sniper fire. It's not difficult and it's effective.
Your approach for a suggestion is also quite bad. Instead of constructively criticizing the LR, you, presumably after being sniped by people and ragequitting, suggest that we get rid of it. Have you tried to use it yourself? It's not that easy of a weapon, unless your opponent makes it easy. I could easily make a post saying "BAN TEH CHAINGUN!!1111" after playing in a game with Mabel. In fact, a lot of newbies did QQ about the CG. Nowadays, there is a lot of complaint about the mortar, and guess what? The dev team decided to give the mortar an arming time and reduce the explosion radius. That's a constructive improvement.
If you have a gripe with a weapon, focus on ways to constructively do something about it. Outright removal of a weapon is a last resort effort and shows that you put absolutely zero thought into your suggestion.
