I’m thinking for now 4 troopers minimum is a good staple for starter armies and the more the better.
Grappling hooks are great but, it’s all based on the terrain of your play space. Obviously if flat mat terrain with little to no buildings then you could cut the points. Great way to not needlessly die to your own dice if on a dense cityscape though.
The laser cannon probably limits you the most in the list and I would consider swapping them out for rotary cannons. A majority of your problems will be dealing with troopers and enemy Luke/Vader and those pesky unarmored speeders. Flamer is an excellent choice and will work wonders for you in all scenarios.
I personally would swap battle meditation with Jedi mind trick, Luke gets in close, and if you can suppress a full squad before shooting you, you’ll be able to better your Defense with their inability to do two actions.
Cut long range comlinks and try and squeeze in some more trooper add-ons and possibly a another heavy weapon.
