Well, my thoughts:

1) I really don't mind. I hight doubt these Squadrom members will be on par with actual players, and I highly doubt you'll be able to complete the latest (expert) dungeons with them.
2) They don't work for trials and raids.
3) If it's for low level dungeons, then I don't see the issue.
4) If this game taught me something with the last job quests, is that the NPC's AI seem to be sometimes better for mechanics than actual players. >.>

The system may as well hold a separate reward pool for those using this feature. Until then, and probably until the upcoming Live Letter, we can only speculate how this feature may (or may not) steal the "Multiplayer" perk of this game.
