Wind blast and force lance

[Lavandula]

Wind blast and force lance attempt to push its target away. It's strange that they move away target, but not the caster. Force lance is the only escape spell in Conjurers' book - wouldn't it be more reliable if it pushed both target and caster in opposite directions?
Also, it's strange that there needs to be two spells with similar functionality.

Wind Blast is not castable by the player.

Are you implying the problem with these two abilities is the lack of conservation of momentum? (edit been a long time since physics)

I don't see a proposal in this post. Edit: you are now proposing to add a self pushback to force lance.

Also magic > physics, there doesn't need to have conservation of momentum

How many tiles? Does number of tiles pushed scale with spellpower? Is placed pushed to reliably opposite direction of spellcast, or does it have some variance with where you can land? Force lance can miss the target. Can the pushback miss? If you get pushed back into a wall, do you take damage? If you get pushed into a creature, does it take damage?

Also

Putting a self pushback into force lance is a -significant- buff. I am not convinced force lance needs a buff. Can you justify Force Lance remaining at spell level 4 with this change?
