This is what I think is OP for a first level gish.
That said, so far in the 5E games I've run, this probably wouldn't have been a show stopper. Maybe just some pangs of jealousy :)
My players did have a hell of s time against three perytons though, (resistant to non-magical normal damage.) Fourth level party of five lost a member since all the melees were only doing half damage.
Changing the subject, how would Swordmage fit into 5E's multi-classing rules?
