Mercs are a good feature executed badly. I don't see anyone running around with an average small gun merc. Or even, crazily enough, two or three.Too expensive, too easily lost. For exceptionally wealthy level 21s only. Too much of a gamble for anyone else.
Slaving is great if you want to die in random encounters and lose everything all the time. Can't go near BOS or Unity without getting murdered and the trade off is bad followers that take about as much time to get as the time it takes to make caps to buy a merc.
Ah your just starting off mate, don't worry, once your about level 9 and have at least 100% outdoorsman you'll be a much happier slaver .
even with 150% outdoor you can still get into encounters and pretty much all the good towns are in deadly areas. NCR rangers, unity and BOS covers pretty much everything but the north and sf.
I have 249 and that is not enough for me.
I heard last wipe that at 150% the encounter rate caps out and anything past that is just movement speed.
