Yes, definitely reaching at least +100% magic find should be a target.
tho it should NOT cost the majority of clear speed (damage) and defensive stats (resists,health)
Doing boss twice (dps focused gear) in same time as
one kill - when dressed to magic find - may actually favour more repeats with no Magic Find.
I said ~may~.
Yesterday i tried to do some runs - new ssf char on route:
(normal) travincal, sanctuary, bloody wp and Baal
Guess what? -> no Unique drop xD
But! i got to lvl 40, covered some missing resists - to start next difficulty with about 40@res,
found sufficient Rare gear worth to spend my socketing essences on.

As mentioned above by Lucid: "...Damage really isnt a big problem..."
- it's more bout sustaining incoming damage (ways to regen/replenish/leech Health back
& Avoiding/Disposing of negative status effects like: Frozen -move speed, -attack speed and Curses -resist etc.

! DEFENSIVE STATS:
sooner or later lack of defensive stats will make the game hard, preventing progress
- taking away satisfaction, wanting to change profession, making a new character.

! MY PRIORITIES - (things influencing imo ppl forget/discredit )
1 Cold resistance - greatly influencing gameplay slowing move and attack speed
- the more cold resistance you have - faster "chilled" status will expire;
2 Lightning resistance tends to hurt the most due to big maximum damage
+ applies "shock" - making your character stop/cancel attack or move order

*Faster hit Recovery - defensive stat determining how fast - after action cancelled -
your character will be able to "regain balance"/recover after it got hit
this stat is imo more important for melee fighters but eventually
every char (before being able to facetank/oneshot Bosses) should keep it's
class's breakpoint as high as possible. I'll set a link (i hope it's up to date):

3 proper potion mods/usage.
4 Using/gearing mercenary

! POTIONS:
There are lot of negative status effects received with incoming damage, like:
Frozen, Amplify dmg some monsters even have auras lowering your combat stats.
I look to have mods on my potions:
- Cannot be Frozen
- Curse immunity
- Physical resistance
also mixed with +Hit recovery, Increased Duration/Potency, Max Health, Health Regeneration/or Per Kill.
It's not hard to find/ make your belt to have situational solutions against things that lower character performance.

! SECOND SET:
I store every Unique item
(they can be upgraded and also warped - risking breaking it or getting a game-changing mod)
There are also a lot of synergies between certain Uniqs which may not have been noticed on first sight.

Rare (yellow) items with over %15-20+ Magic Find i try to fit in - selecting balanced dps>mf set.

Also It's very useful to check your Character Screen[C] while Cursed or in range of enemy's Aura
to see what stats/resist should be fixed - helps t understand "why we fall".


Wish You luck and hope some of my tips can help/solve some difficulties
- Overall: repeating is key to mastering.
