So, MF doesn't increase my chances of finding runes or gems? I basically have to get to Hell lvl and just keep playing until my hair turns grey?
There's some minor things you can do to improve the odds abit, but that's pretty much what you'll need to do yes. Put basically, the key to rune hunting is quantity, not quality. Taking most of the MF gear from your character, and focus on killing power will allow you to kill more monsters is less time, which will slightly increase the chances of you finding a rune.
Also, killing monsters in a higher player count game will also slightly increase the odds of a rune dropping since it'll reduce the odds of a no-drop on that monster. This will have an adverse effect on the Countess's special rune drop though (if you plan on running her), because her item drop is rolled before her rune drop.
That said, having just 1 extra person in the game won't make any difference at all, unless that person is in the same party as you, and within two screens of each monster you kill. When determining the amount of players to use in the "no drop" of a monster, the game basically does this:
1 + (1*AlliedPlayers) + (0.5*UnAlliedPlayers)
AlliedPlayers = People who are in the same party as you,
and within two screens of the monsters death
UnAlliedPlayers = People who are not in the same party as you, or who are but are further than two screens away.
This means that if it's just you and another person in the game (and the other person is somewhere else), each monster you kill with have 50% more life, but no greater chance of dropping a rune than if you were in the game yourself. Likewise, if your in a public game with 7 other people who are doing a baal run or something, while you're runehunting, the player count used in the no-drop chance will be: 1 + (1*0)+(0.5*7) = 4 players.
Although this might sound bad, unless you're running with friends it's generally better to do solo rune runs in a public game, because you don't want that Jah rune to finally drop and having it grabbed by some random person. Also, if you do focus on killing power instead of MF, then doing solo runs in a full game shouldn't be too difficult, or time taxing.
