High Rune drop rates are greatly increased on the server?

Increased drop rates only means that bosses and some special area mobs like pindle have a higher chance of dropping more uniques and solo farming is as rewarding if you would use a full game.
Drop rate of runes is just normal drop rate and random.
Can get 2 jah in a day or go weeks without finding anything. Its all about luck.
Also mob density and frequency you farm will help a lot with finding runes.
High populated areas like worldstone keep or cows will have better chances of finding runes compared to areas where there are hardly any mobs.
And with frequency, well someone doing 40-50 runs an hour will have a better chance of finding runes/items than someone doing 15-25 runs an hour.
Like i said earlier, all about luck.

@SorceCode, not sure where you've read that but the mentioned rate is incorrect. I recommend you don't rely on those kind of numbers anyway and just enjoy the game.
Besides what @inayat mentioned in his post, keep in mind that in here drop rates alone will be as you'd be farming in a full game already but other than that it's all about fast clearing, mobs density and luck.
Also, hearing and actually seeing it are two different things but you will have a higher chance of getting a zod rune for sure in here unlike in battlenet.

 

Blizzard increased the drop rate of high runes in 1.13 compared to older versions so that rate is obsolete. Mobs density, fast clearing, frequency, luck and repeat is all you really need to focus on.

 

As @NaBelea mentioned, "/player x" command is a single-player mode only command and does not work in multiplayer mode. If you wish to run solo baals for experience you can simply open more loaders.
