Its an old post,but I only read it yesterday.

I was going to ask if you had done the research  yourself  but it seems not, at least you had the deceny to post the link to your information source.

Though no doubt you gained useful information from the links you gave.

I would suggest that without corroboration of the information the youtube link contains, its a disservice to players to post it as fact.

The introduction of Ubers and other changes  will have affected things considerably.

I dont doubt the you tube player knew /knows how to play the game,but am doubtful about the accuracy of his research or its relevance then or now.

The research and video was produced in 2016 ,when he was quite advanced in his game ,,

One of his replies to comments about his video says this.. .... "I can only test for what i have."

Thus admitting  the research is really only relevant to his circumstances at the time he did it.

Whats the point in telling someone who has just started playing?.

" Attacking level 1 invaders is the worst option and you should attack level 6" 

Lots of advanced players are attacking level 1 invaders  so there has to be a reason for this.

Very good post but I have to disagree about what you said about legendary standard equipment, some of the legendary standard equipment has larger boosts than any of the legendary invader equipment. For example the victor's Bracelet has the second highest building boost in the game higher than any invader equipment you can craft the only equipment with higher stats is Bjorn's Goblet which is special equipment. Same with learning speed Falcon Figurine gives the third best stats in the game for learning speed only behind Olaf's Seal and Harald's Blade which again are special equipment, The Yarl's Helmet, Heathen's Armour  and Golden Boar give you the biggest boost to food production out of any equipment and they are standard Equipment.
