Yes, we all do...it was just funny how you asked. But, from me, yeah totally. If you can raise it then by all means do so. And/Or, call your roofer who did such a horrible & woefully incomplete job.
You'll have to greatly expand your puddle zone in order to keep everything not only sloped toward the scupper but also toward the center or the line of the scupper. Think of the roof as a sink, shower or tub, but the drain's not in the floor. You MUST have 2 pitches to direct any & all water to that single point.
Now, the raising issue. Of course, shim & re-shim as you raise & until your happy with everything. But, once you feel the job is complete you MUST re-secure the roof with short screws (1/2" if you don't know the thickness) into the roof decking & nails or screws into BOTH sides of the joists.
You should use galvanized bent Mending Plates or L-brackets. You want, at least, as many bracket points as there are nails that you backed out. FYI, the best support would be to cut the nail shanks off with a Dremel & cut full length wood wedges to replace your shims. Finally, glue everything that you can for best re-connection & to also ensure that shims don't fall out over time.
