I would have preferred "Magic Bolt" (or maybe a variant Magic Missle).. kinda like the Warlock's Eldritch Blast.. does force damage so as to be elemental-ly neutral..
Javelin of Fire isn't the only wizard at-will, there are others. I would be astonished if Magic Missile isn't one of them - it seems a natural.
I'm not real enthused by the 'mother may I' style of play, it /is/, as you may have experienced, very dependent on the skill/experience, personality/talent, and mood of the DM.
Also the return to relative incompetence at level one isn't inspiring. One of the things I liked about 3e and 4e is that they made the PCs of an Heroic Fantasy RPG more heroic from the start.

I really dislike the fact that the casting mechanics are diferent from attacks, a missed oportunity to make a more unified game. One more cool thing from 4e that is abandoned in 5e.
