heat will make you a litteral sitting duck and phys will destroy you without any gimmiks.
energy makes me ANGERY because most weapons use energy and i like a lot of them.it makes you seem powerles unless you have anihilation graple hook.
the 3 ways of getting rid of those RATS is to use heat and keep them stunlocked with double heats,use energy counter or kill them before they get that valant snoper on your sorry ass.
or just keep them close. their most efective way of killing you is valant snip snop.
of they have EMP get the away and if they have both well,abandon ship.
