I have over 505 MF and can clear all of the major spots solo A1-A5. I have been trying out the Easter egg as of late and it almost seems negligible, please teach me your ways and I will pay up to 12fg based on the value of advice. I have tried Easter Egg with Terror zones, on it's own, only with my designated run, etc and I am not seeing a noticeable difference.

kill stuff more faster

Have you tried youtube or google? There has to be dozens of videos and hundreds of posts explaining this in great detail.

after 300mf, anything above that has diminishing returns meaning clear speed is more important so you can get more runs done. after that you need more players in your game vs solo, you will get more drops in even players 3-4, doesn't have to always be players 8.

Yes, I resorted to that first and nothing seems to move the needle or I just have incredibly horrible RNG.

At 505 MF, the easter egg is bringing negligible returns. In fact, at 505, you are already well over the sort of "recommended" soft cap of ~350. The biggest factor is player count.

Its better a gg dmg, keep 200 mf and kill more monsters
Also, p3 games help a few

I guess I have a hard time balancing survivability when I more than one person in the game with my MF. I am lvl 92 blizz sorc and can do Baal runs with full party no problem, but only because they come in to help at some point. I feel like if I am MFing on my own in a full party I will get wrecked.

Well I reported that so..
