I am ready to purchase a new gun, however I don't know which one to get. I like the Trac S because of the option to have the underbarrel grenade launcher, how useful is it really? If I shoot a grenade into a group of enemies will it just damage them or get a bunch of kills? How does the Jaguar compare to the Lynx? I plan to get a reflex sight on the gun, and mostly I end up in CQC situations, when assaulting Bio Labs or Tech Plants, however I do end up in quite a few fights that aren't right on top of each other, mainly in the more open bases when jumping between buildings. Thank you.
