A lot of words, but you basically agree with me when I say Conjurers conjure jack skit until mid to high levels, right?
Not really. You don't conjure up creatures, but grease puddles, fog clouds, swarms of daggers, spheres of fire, webbing, ice storms, stinky clouds, and more can be conjured before you hit your 4th level spells at level 7.
And if you look at the conjurer's archetype features, something that stands out is that his summoning boost features don't even show up until later on -- a design hint that acknowledges the lack of early-level summoning spells. Personal teleport & conjuring minor items are useful too.
Also, I don't think your familiar qualifies as useless, even at lower levels. Those 30 extra temp HPs are enough to make it actually survivable in a fight. Not highly so, but... not 'lets get the nuisance out of our way in a single move' survivable either, anymore.
