SO on a scale of 1 to 10 how bad of an idea is support Swain??

I got salty that i got placed as support even though i queued for it (I know im garbage i just felt like actually dealing damage that game) so i troll picked support swain in ranked (shoot me.) Surprisingly enough it worked out really well, and we ended up winning and i got honored after they flamed me for trolling and proceeded to carry the mother fuckers. it was basically support brand but i wasn't "accidentally" taking kills. Basically built damage support (50/50.)

I'm probably not going to do it again outside of normals on occasion, but is it some hidden korean thing or should i keep that in the trollpick vault?
