ok there is the answer about thing i heard
"Shield Improvements: We’ve changed the way shields work to allow them to absorb any incoming kinetic or energy damage regardless of the source (melee, ranged, Force, tech – doesn’t matter). This has significantly increased the importance of shields, and the game has been rebalanced to account for such a major adjustment."
