Can anyone give me tips on clearing these missions easily?

The pack of Jawas hit pretty hard with their aoe and single attacks I can barely survived till the 3rd round with a whole team.

I only managed to beat 5-I with pure luck. (Couple of lucky revives from old daka and allied boba fett) but 5-K was really awful with Old Ben added at the last round.

Current lineup:
(level) [gear] name #*
- ability levels by order

(52) [6] Talia 4*
- 4:4:3:3
(52) [6] Darth Sidious 4*
- 4:4:4:4
(52) [6] Old Daka 4*
- 3:3:3:4
(52) [6] Count Dooku 3*
- 5:4:4:4
(51) [5] Royal Guard 3*
- 3:3:2
(50) [5] General Veers 3*
- 2:2:2:2
(50) [4] IG-86 Sentinel Droid 4*
- 3:3:2
(50) [5] Asajj Ventress 4*
- 2:2:3:2
(40) [4] Nightsister Initiate 4*
- 1:1:1
(40) [4] IG-88 3*
- 2:2:2:2
(40) [4] HK-47 4*
- 2:2:1:1
(40) [4] Cad Bane 3*
- 1:1:1:1
(30) [3] Snowtrooper 1*
- 1:1:1
(30) [3] Nightsister Acolyte 2*
- 1:1:1
(30) [3] Geonosian Soldier 2*
- 1:1:1

Initially I tried to power through with Talia, Sidious, Daka, Dooku and Asajj which works through the 1st 2 rounds but fails in the last rounds with the continuous aoe by the 5-6 jawas.

I changed my tactics a bit and changed Asajj with Royal Guard to provide some defence to the team but it still comes up short.

Should I focus on different chars or get new ones? Or just focus on upgrading gears and abilities to the max?
