UR only works imcredibly well on shotgun style maps, ive tried it on widows court, all i have to say is i got pretty angry. But trying to use the last word on widows court, not as bad, but still a pain to use and carry on that map. But like the person who posted this said, learn to use them before you trash them. I personally use either mida/sniper or tlw/sniper on almost every game i play in.
