Mountaintop DOES one shot on direct hits. That’s you being bad and missing or possibly a glitch which won’t be consistent. Pvp is fine solo again you probably just aren’t great. I play mostly solo and I’m in the top 2% it’s fine pvp is the most balanced it has every been meta wise oh wait I have a copy pasta for this
High impact pulses kill faster and have more range so they win the long range duel. Burst Sidearms kill much faster at close range winning that duel.
Handcannons don’t kill faster but they win the duel if they peak shot. They have strengths weaknesses and counters. That’s how guns should be if you ask me
