Last few days I play only new TSAR maps due to operation campaigns. I generally like all classes (despite Support actually), but I was bad with bolt-action rifles before and decided that russian maps are good occasion to improve my Scout performance. After playing Scout nearly as much as I played as Assault and Medic before - switching classes feels bad.
Scout weapons are generally the only ones that actually feel powerful. You don't always kill with one shot, but you rarely do less than 80 dmg and you know that your bullets are bullets and not jelly beans. SMGs can trick you with it's RPM, so Hellriegel or Automatico feel powerful enough, because in CQC enemy melts fast. Medic rifles... well, sometimes they feel powerful, and sometimes you start to wonder if this is actually a gun or toy. Federov is generally good in CQC, but at a little bit longer distance it's pretty laughtable. 1... 2... 3... 4... 5... bullets WTF, this guy is still running. Is this even a weapon? Not to mention LMGs. Omg these are completely terrible. After getting used to spreadless, powerful bullets of bolt-action rifle it's like someone punched you in the face. You not only need like half a million bullets to kill a guy but also these bullets fly basically everywhere. Only MG-14 feels like actual LMG and despite it's huge recoil (you would expect that from LMG actually) it's the only LMG that truly does it's job by ripping people in half at generally any distance. BAR or Chauchat are assault rifles rather than LMGs to be honest.
I was SO BADLY ANNOYED by RNG spread after using bolt-action rifles. With bolt-action I always know that it was my fault that I missed a shot. With LMGs and many SLRs it's more random than skill based actually.
Hillhumping is still a bad thing, but I'm not suprised why people don't want to use other weapons.
