this is an interesting topic.
one that i have spent most time trying to figure out.
scientist at work 
but jokes aside,
i don’t deny that having bots with better gear could make things interesting.
( which for those who is interested here are some of my experiments, )

so, as showns and can be experienced,
in order to make bots remotely interesting ( imo ), both their squad composition and gear should be adjusted.
mainly expanding the number of bots to 12, and give them gear br III+
but on the other hand,
as it can be somewhat experienced even now with these lacklaster bots,
players will get access through br III+ weapons in br II / I games. ( granted, not often, and you have to be lucky to be alive when the bots dies )
but this would let players use
fed mgs, stgs, svts, 30 cals, etc etc ) which it’s not great for the pvp side.
and, another major factor is,
how would you balance bots.
to be both effective, but not to exagerate.
in my opinion, historical loadouts would solve partially the issue.
but i’m not sure developers would go to the extend of modifying the bots presets ( which originally, they did planned )

but, it all comes down to:
this game is primarily pvp.
and as much i’m the biggest proponent for pve content, it is not clear if enlisted will ever have pves.
i can remotely show and prove that pves titles can be popular ( just to name few, helldiver, risk of rain, space marine 2, yada yada yada ), the influx of gamers, and how the skin department as well as other goodies related for that mod can bring substantial income as well.
but ultimately it boils down to the developers themselves and/or higher ups.
and last thing,
bots in enlisted are rare.
you think you have bots in your team, but no, most are just very inexperienced or new players.
so, ideally you would make bots better and stronger.
but it wont serve much because you wouldn’t meet them very often.
and if you do ( which ideally, bots would replace those quitters, their effect won’t be able to make up for the players themselves ) they will not aid anyone in preventing the inevitable.
