After playing a Summoner in a one shot with a Beast Eidolon, I don't think frontline Eidolons are my thing.
So now I'm considering playing either a plant eidolon or a ranged combatant eidolon. With the Plant, the eidolon can more safely hang out behind actual frontliners but still offer tripping, grappling, and occasional flanking. With a Ranged Combatant, the eidolon can only attack but from even further away with no need for the size increasing feats or spells.
I'm torn between the two, but even before we get to that, are these even good ideas to go for? How much am I missing not going for the typical melee frontline Eidolon? I don't hear too much about the Plant Eidolon so I don't know if its reach gimmick is just that, a gimmick. Same thing for Ranged Combatant, and I was looking at it in particular for the Fey Eidolon. I don't know why I'm drawn to all the primal Eidolons.
If it matters, our party hypothetical party comp atm is: Fighter, Champion, Bard, some ranged martial (it's likely between Gunslinger or archer Monk)
