I mean, the short answer is - don't use them on either. Yes, theoretically, 1+1 has the same odds as a 2x weekend. But you'll feel the pain significantly more on the 1+1, because of the lower odds of actually having it work. The exception to this is if you're at mercy counter, where the value of 1+1 is *significantly* higher.

As for the 10x, you should basically never participate in those until you're uber-endgame.

It depends on your needs but it is probably best to wait and pull them during a fusion event unless you have plenty to spare. Fusion champions are usually some of the best. 

It really depends on how many champions that you want are in each pool but in general the 10X gives you a better chance of pulling the champion you want but it is still terrible chances. For the 2-champion event your probably that you will pull a spacific champion is around .5% since you can pull the same champion twice. Now if you want 20 champions in the general pool your chances of getting one you want is just as good as the 10X event. This is because there are slightly over 200 legendaries. 

As noted above really depends where you are in the game.  If there are still epics that would drastically benefit your account never pull outside a 2x.  Generally I don't advise anyone pull outside 2x anyway, unless they know they'll hit mercy or are very end game.

Thanks for the replies.

The reason I ask is I track my pulls so I know how close I am to a guaranteed Legendary.

As it stands I'm 31 away from a Legendary with Ancient shards & have the number of shards I need to hit the guaranteed.

I mean - in that case you're probably well served going for the 1+1. Even if you do get a lego, on the 10x you've still only around a 5% chance to get a specific targeted 10x champ. And as painful as it is to get a terrible lego, it will *eventually* prove useful as you start to fill out your roster with more guardian hall champs.

so you know when you hit mercy  the chance increases  by 2% per  pull meaning you would  need to pull like 48 shards  once you reached mercy to be actually guaranteed

I mean unless your already well into mercy

But as we all know most pull a lego well before these  numbers

Assuming I've done my calculations right it's maximum 220 pulls for Ancient/Void shards and 56 pulls for Sacred shards before you're guaranteed a Legendary?

I've pulled 189 Ancient shards since my last Legendary pull, so maximum of 31 more pulls to get a Legendary.

you are correct :)

not sure why I thought  it was  only a 2% chance increase

actually a 5%

good to know ;)

Glad I decided to wait for the 1+1 promotion.

Took me to the 198th pull of the maximum 220 on mercy, but just pulled Cupidus and then got Helicath as the bonus legendary 😎

Grats! Definitely should look into whether Helicath can enable an unkillable CB team for you.

Thanks.

Yeah i've seen mention of unkillable teams with Helicath, need to look into whether it's viable with what i've got.
