Many people cry foul at weapons like polaris, FF, BTB or voltaic tempest. (some whine about the hammer, but thats nowhere near OP)
Lockdown is balanced, purely because people, as players, are imbalanced. Many people would rather blame others, instead of confess to their own shortcomings, whether it be a slower reaction time, or failure to pay attention.
THE WEAKEST OF THE HERD WILL BE KILLED SO THE HERD CAN MOVE FASTER.
It's also because of failed teamwork. NEVER go off alone, always try to have at LEAST two people to take a base.
Always equip accordingly to your team mates if possible.
For example, one person shocks with a polaris, while another striker with WHB, gets behind him and cuts him up while he's convulsing.
TL;DR
It's not the game, it's you.
I never try to go out with people, if it happens it happens but i go the way i feel is right even if it is alone.
