Best ways to defeat Imperial Troopers?

It all depends on the mods. If they're faster than your Wampa you're toast. Ability block, no ice breaker, no counter. He's dead faster than you can blink. Same with Finn/Poe. Starck is inherently faster by a good margin (+25) so you really need to out mod them.

With Troopers you need to go first against them without using one of the big 5 teams listed above.
