I honestly feel like the SMG is a slightly unused and very under-damaging weapon to Hale. As I have seen, SMG with crits does 24 damage per shot, an entire clip equaling only 600 damage, and most of the time the average player only hits around half of the clip on Hale. Is that satisfactory for what the sniper rifle can do with a single fully charged shot? Not at all.
I feel a damage buff would be in order for both SMGs available for the sniper. Maybe about a 80% increase in damage for the stock and 100% for the silenced SMG due to the slower fire rate and smaller clip capacity. That would raise it to just about double that of what you could previously do damage wise and make you a tad more of a threat to Hale at close corners, alternatively it could be used at medium range to knock the Hale back from a jump. Many different possibilities for this certain buff I am describing.
For you that do not know, am a pretty active sniper when I play TF2 (not hale speaking), most of the time I do enjoy using the smg, it makes it a bit more of a challenge and less like "I'll just plop down in this one spot and shoot fellas..." That really is one thing I would love to see, snipers going all-out on hale with only a smg, being more assault than support in some way. It works well in vanilla.
Well, that's about it. This may have already been thought about or even suggested at one point, but I can't seem to find anything on the forums. welp, already got this typed up.
Take care everyone, thanks for reading this little idea I had last night. - Nova
