Defeating Iokath Sentinel Droids

Main story quest on Iokath 'Showdown on Iokath' required you to use walker to destroy 3 Sentinel droids after you kill Acina/Malcom. It is very annoying.....

What I did

Beating it at its level is easy but when you're overlevelled it gets annoying.

Use overcharged beam and stomp in alternative pattern, targeting 1 droid at a time. Keep moving around as to avoid taking ground damage.

Once you have destroyed one unit, type /stuck in chat box to insta die. When you respawn click "Launch" option on right top to get back into fight, only this time there will be 2 droids left.

Do the same step all over again, till you destroy all droids. You need to spam skills asap as the droids starts respawning.
