Sausage fest environments are bound to be disadvantageous for men:

1- Women have their pick of the litter and will default to Chad-targeting mode, because while women naturally value personality, but with an abundance of guys making good personality men no longer being rare, the good personality AND good looking men get picked.

2 - Women pick the men first and you are game over'ed before you even start approaching.

3 - You have to deal with orbiters before you can even make your approach, because chances are you are not the first one to notice a girl.

The solution is for men to change their usual social environments to places with healthy distribution of male to female or even female dominated place. Men will still have to work on their personality, mindset, mannerisms, appearances, etc, but changing environments will make dating much easier for them.
