"What's the meta situation of Eeveelutions?"

#PokemonGO: My question is:Are Eeveelutions worth it? I know that there are better Electric, Fire and Psiquic 'mons, but overall, is it good to have an army of Eeveelutions?It's more like a preference AND looking for a good setup of attackers and defenders.Edit for clarification: I've seen a few posts of people asking about specifics, like Umbreon etc.. My question is more an overall about both available and future evolutions, but mainly about those available via /r/TheSilphRoad http://ift.tt/2fgKKQX
