In general, some summary:
1. Jedis are definitely overpowered. Especially force push - my consular ran through the whole game without using its lightsaber, even with final Malak.
2. Non-jedi members CAN be very powerful, but in the second part of the game, and if they are blade fighters - blasters are definitely underpowered.
If you want more fun, play the whole game on hard with Zaalbar and Mission only
What Obsidian should do? Better balancing:
1. Give more power to ranged weapons.
2. Reduce the power of some forces.
3. Improve enemies - more use of medpacks, more grenadiers (it is fun to be hard hit by several plasma grenades ), jedis should use more frequently their force powers.
