So basically, the ritual gives you a very slight increase on the very low odds of dropping a sunder from the normal TC (when a gc is rolled as unique) but does not change your odds of rolling sunders from the herald's TC.
The ritual as close to no incidence on your odds beyond heralds lvl 1-3, which is why you run full TZ games, ritual or not.
And that very small increase you can potentially get from the ritual is probably resulting in less sunders per time played rather than just skipping that step.
Nothing new was learned here.
Same old d2 influencers cleaning the dust off of old topics cuz they have nothing new to come up with to get views.
The conclusion is
if you run p1 without using shards, your odds of finding a sunder are horrible
if you run p1 to p8 and use 1 shard per game, you prob can get to lvl 5 heralds, but you're done once it starts to be rewarding as all following heralds in the next 4 acts would have been lvl 5
if you want good odds of finding sunders, you need to set the whole game in TZ, and ideally on higher player count, and you can further increase your odds with a horker in your team
mf has very low incidence on all this
running coordinated p8 is not accessible to everyone
running for as long as it takes to clear full games is not accessible to everyone
not being able to combine both the above means most sunders will come from either bots, or teams of human nerds without a life
But now... if you value more sets/uniques over bases, then performing the ritual could be worth it for you if you plan on doing a full game clear. Not a big deal tho. But I guess that the addition of a few new valuable uniques (new ones and old ones) has slightly shifted the effective value of having more mf%.
In the current state of the game, it gives a huge advantage to warlocks who can easily deal with immunes.
It also keeps LoD farming alive, for the purpose of having much easier access to the old sunders.
IMO, the difficulty of obtaining a sunder as it is right now would be nice IF no class was able to deal so easily with immunes as the warlock, and IF the old sunders couldn't be converted, because it would force team play.
But as it is right now, it only creates huge gaps between classes and players. And instead of encouraging diversity and team play, it forces very strict meta strategies that are only accessible to bot farms or dedicated teams, while solo players (even those willing to play in open games) are left behind.
