I think with SB SE kinda tried to give the players what they were asking for:

"players: give us bigger egis" > "devs: here take Bahamut himself" > "players: I can't see mechanics, make it smaller" > "Devs: ..."
"players: smn is not a dot class" > "devs: here you are down to 2 dots which are super easy to keep up" > "players: where are my dots?" > "devs: ..."
"players: let's have the egi buff the party" > "devs: devotion, contagion, radiant shield" > "players: not like this" > "devs: ..."

I guess at this point they don't really know anymore what to do with SMN. I'm not surprised the job doesn't work well
