Urgot auto attack changes

Having played both new Urgot and old Urgot I have come to like his rework both in theme and gameplay, but I believe there is something wrong with the champion in regards to his auto attacks and his (W) purge ability. Urgot's regular attacks without the (P) echoing Flames feel pathetic and weak, on the other hand his (W) purge feels good to use but the damage is about three times weaker than auto attacks; meaning he shoots about 4-6 shots a burst with three times the fire speed but one-third the output. I believe Urgot would feel better to play if his regular auto attack had a new sound effect that felt more powerful with a different projectile that gave it a slight oomf to it. My friend suggested something that sounds like a rail gun but fires with a high caliber bullet, this way his auto's felt stronger while his purge would remain the same as he alternates between tank buster shots and machine gun fire. The animations are already present in his auto attacks for something that is stronger than what he uses, and unless the idea is to feel pathetic without echoing flames I think the change would make him more enjoyable to play.
