Same logic can be applied for using Omphalos Bullet to Wildfire. What would you tell someone suggesting that tho?
Leaden Salute and Slug Shot are still extremely powerful weapon skills even at 99, so why don't you use them instead of Wildfire and Last Stand on your COR? That's right, their days of glory have faded away now.
Look, Thief is a guy whose uncle has just kicked the bucket and his share of the Will turns out to be a Porshe. The Thief guy has been actually into cycling his whole life, but freebies are freebies, so, whatever. Could use that Porsh to pick up some chicks, hit the beach or something. Then the Thief guy gives it a try and turns out the red Porsh won't even overtake his neighbour's rusty Volkswagen AND holds tops 0.5L of fuel. So the Thief guy starts to wonder, wasn't this three legged red mustang supposed to come with a parcel of NOS toolkit and a modded tank or something?
That's where Thief stands right now. I'm asking for some decent gun/crossbow and some decent ammo so that Thief & The Last Stand becomes more than an old man's last prank. We didn't ask for it, yet here it is. So, please make an already sidegrade weapon skill requiring 1M xp and locking you out of other 11 choices a worthwhile endeavour for Thief.
As of now my thoughts regarding Last Stand can be summed up by this pic:
