Jewels make the tree feel homogenized, consider following poe1's model

Making builds in PoE1 would be way different if you added more jewel sockets and added aoe/duration/etc to the jewels. Would have probably cut its lifespan by half.

Nobody in trade gives two fucks about the placement of AoE/duration clusters at this point, which is kinda sad.

I'm sure PoE2Ninja will illustrate the problems more clearly once the API is released.

PoE1 has a total of 21 Jewel Sockets, without the "Scion Sockets" it's 18 and only 12 if you exclude the 6 "3-point Large Cluster Sockets".

PoE2 has 24 Jewel Sockets, period.

And yes, you could use a "Large Cluster Jewel" with 2 additional Sockets on it, but that would result in +1 and not +2 because you use the slot for the "Large Cluster Jewel". It's extremely worth tho, because "Clusters Jewels" are stupidly strong, but you get the point.

So, if you want to get "even" you need 3 "Large Cluster Jewels" with +2 each to get the possible 24 Jewel Slots as it is in PoE2 atm. (Obviously excluding rare cases)

There are probably some good mods we are missing in PoE2, but tbh - I think jewels are in a good spot for most builds.
