I know you were talking about generalist builds that include summoners. The point I was making is that a generalist armor, balanced to include summoners, doesn’t fit well.
Either your benefits to summoners are viable and then the armor set becomes too powerful as a whole due to mixed class summoner, or you end up with a set that is really only viable to hybrid summoners (note: this wouldn’t be bad per se, but then it isn’t generalist anymore), or it holds no niche for summoners and ends up being a melee/ranged/magic armor set with say an extra minion tacked on.
That’s the thing with summoners relying on numbers of minions as their source of damage. By offering, say, +1 minion, then the player’s main damage source becomes their melee/ranged/magic weapon, but by offering +2 or +3 minions, their main damage source is suddenly their minions. You either have a generalist set that discludes summoners, or a set that isn’t even generalist anymore. This is also why it’s so easy for hybrid summon builds to boost too much and end up being too strong.
For example, about a month ago I did a ranged/summon only run. My hybrid build of Spooky Armor with Red Riding chestplate that I had a recent playthrough, available the second you kill Golem, was VERY close to broken.
Example for the second problem is Forbidden. Personally, the set bonus is nowhere near worth all the sacrifices from Mage build, so it still becomes a Summoner armor with Ranged focus. Another one is, as qwerty brought up, the Hallowed Hood - it’s a summoner armor set, not a general. Yeah it provides universal boosts, but they are so small it turns into exclusively a summoner set. It’s not a bad armor set... but it isn’t generalist.
Example for the third problem is pretty much any OOA armor set. They provide hefty bonuses to both x class and summoners, but the bonuses they provide to summoners aren’t enough - no extra minions, and sentries on their own suck. Unless you’re using the OOA sets as I did for the first example, you really only use them to min-max melee/ranged/magic.
There are sets or combinations pretty close to a generalist set that includes summoner already - close enough to be used as an example - and they all show that although it’s cool on paper, it’s very very difficult to make a good generalist armor set that includes summoner
