I.think I saw it posted on Reddit that normal 3 is.the most.energy efficient for points?

Even if that would be the case, I would definetly not run normal 3. You would get 0 usefull artifacts from that.

Have they reduced the number of points for Lego items?

A six star Lego was worth 20 points when I just checked. Has it always been 20 points or was it 25?

it's always been 20. it's worth 25 points in a tournament, which is where i expect the confusion is coming from.

Thanks, that makes sense.

What's the best option for newer players who haven't opened up the Hard mode dungeons yet?

The highest stage up to stage 20 that you're able to do.

Very much this :D

Maybe so, but if it were the case, that could help lower level players who need DD points more than aything, especially as there's a 4 day DD at the end of this fusion with only 1 day of superraids overlapping it - that's going to make it a tough grind for points for many. However, I don't actually know if Stage 3 really is the most energy efficient - I simply remember reading it on Reddit, where of course other people mentioned higher level stages are better to farm if possible because of the rewards. :)

 See kramaswamy.kr post above: 

The highest stage up to stage 20 that you're able to do.  

As stated above, even if stage 3 is the "most efficient" you've completely remove any chance of receiving
something that could be a possible upgrade. Furthermore, you're missing the extra silver from selling the un-needed pieces. 

That's why I love Spider Tournaments. I get extra rewards for farming silver, something I do daily anyway.  

So 0.682 points on Hard10 and 0.7602 on 20. Seems worth it to me to run H10 (which I did for all of divers) just for the mythic gear chances. That's really the rarity that can help my account, otherwise I'm mostly running just to sell everything.

Lol. I'm running 20... even during cvc.  Haven't touched hard mode yet... will wait til after fusion 

Dragon hard10 is super ezmode. Recommend you power thru to it. My team isn't optimal but it is 100%, about 3 min - bek kimi mithrala dark kael ninja.
