[sblock=OOC]Yeah, there is a fundamental misunderstanding here. You have three different versions of cover (Cover, Improved Cover and Total Cover) and I think you are confusing cover with total cover. Total cover is the only one that blocks LOS. Cover (including soft cover) provides +5 Ref and Improved Cover provides +10 Ref.
After you see my point, perhaps you will reconsider things and the Jedi and clones will be back since +5 Ref will leave only one SBD hit and the Droideka missed. This is an example of how I saw the battlefield:
Sonja from cover Force Slams VA-11N, with full LOS and no cover for the target. Look at the green line, they show LOS and you can see that there is no obstruction to any of the corners of the target's square. Sonja has the same with the Nikto.
Also Chase has a similar situation with firing at both the Vodran and VA-11N.
Now look at it from the return attacks. VA-11N and the Nikto both have LOS when you trace back the green lines.
But, when you try to reach all of the corners of Sonja's square you have to pass through obstructions (red lines) so she has cover (+5 Ref). This has nothing to do with wall height either, the example assumes the wall is 10feet high.
Likewise Chase has +5 Ref from cover from both the Vodran and VA-11N.
Chase and the Nikto have Total Cover due to no LOS. Sonja and the Vodran have the same situation.
So bottom line, Sonja could Force Slam a group of SBDs and still be protected from almost all of the droids unless they moved enough to get the wall out of the way. Even from square Y-8 she would have cover from the Vodran and any targets west of him.
BTW, these rules on cover and drawing lines are essentially the same in 3.5ed, PF, and d20 Modern and not unique to SWSE.[/sblock]
