70-130 would be ideal
It wouldn’t be ideal for D4, since your health pool will be considerably bigger than your health pool was in D2. 1200 hp was a normal amount of health in D2 in the endgame, so adding 130 to that from one item is a pretty big improvement. In D4 your health pool will be bigger in the endgame, so for an item to give a similar improvement 1300 sounds reasonable.
Now you may not like seeing bigger numbers, I don’t like what happened to the numbers in D3 either, but I think 1300 vs 130 is not really such a big deal and is similar to what you see in PoE for example. Yeah we saw one character doing 400k crits in beta, but if you watched that video you’d have noticed that those 400k crits were outliers and not the average he was doing. Most of the crits were like 20-30k which is still big, but you have to consider that this is fully minmaxed lvl 35 gear and not the typical damage for a lvl 25 character.
So I don’t think we are seeing any real danger yet of moving into D3 territory of numbers, doing a couple million dmg with maxed out gear in the endgame is not a huge problem imo and doesn’t immediately turn the game into cookie clicker.
