Only thing worthwhile is the 15 @res but even then it is debatable as you can get it from other sources
e.g. Ber / Cham
If you like life you could even socket 2 Jah
or Str/Dex jewels etc.
Many options
technically a summoner needs nothing, not even a keyboard.
Would argue there are more builds and specs where it is BiS than those without.
Light sorc / Java use griffons
Dream pala use dream basically
… well I don’t want to break down every single build and no matter what there are also always some options and those GG helms are so rare that you will 99% always use something like a shako or half gg helm anyways =)
Just wanted to point out that delirium is certainly not a GG option if we split hairs
Great to see that you have an opinion. But hardly anyone agrees
Here is bis helm list for each character:
Java: artisans of speed with light facets
bowa: artisans with 15/40
frostmaiden: mavina
cold sorc: nightwings with cold facets
light sorc: griffons with light facets
melee barb: arreats
trapsin: shako
kicksin: gface with 15/40
druid: skill druid pelt with delirium or jalals depending on build
smiter: gface
zealot: gface
summonnecro: harly shako (or delirium in my opinion)
Some bis cases for YOUR opinion:
warcry barb
fire sorc
hammerdin
bone necro
poison necro
End of discussion
In pvp diadem bis for more builds than that but it’s overkill for pvm for most. hard to get away with some unique item when you have to deal with a dead merc, every element and phys dmg. Delirium is very good for pvm on merc. turning into fetish = death/lots of wasted time for serious farmers of most classes though.
