IF your intention is long range shooting, 500-1000 yards, you'll need the mil-dots (not just for ranging). Depending on the caliber (which you neglected to mention) the mil-dots are quite helpful where windage is concerned, allowing for hold offs based on wind speed.
They also come in handy for expedient hold-off, pop one round, check the POI pick the mil-dot which comes closest to the POI, shift your aim to that mil-dot, as long as wind is consistent, your next rounds will be on target (rather simplified, but ya get the idea). This also works for hold overs should the situation not allow for time to "crank" in your elevation changes, of couse a come-up chart will be neccessary for the rifle and caliber your shooting, like this:
Come-ups in minutes for the 77grn SMKs out of the CR-6724s:
100 - zero
200 - 1 1/2 min
300 - 3 3/4 min
350 - 4 min
400 - 5 1/2 min
450 - 7 1/2 min
500 - 9 1/4 min
550 - 11 1/2 min
600 - 12 3/4 min
700 - 17 3/4 min
800 - 23 min
900 - no target
1000 - 35 1/2 min
BTW, Leupold is only name trusted by myself and most long range shooters.
