By having Parry and Reflect both count as damage mitigation (though not precisely soak since they're unaffected by Breach and Pierce)...
This actually sort of felt weird to me, and was part of my feedback during beta. I feel like those talents should remove soak bypassing abilities such as Breach and Pierce. If you Reflect, you get the benefit of adding soak since 9/10 times the majority of blaster weapons don't have those qualities. If you're going into melee where you will use Parry, you're going to end up facing off against more weapons that have at least Pierce, if not Breach when it comes to lightsaber fights. I found it unfair that essentially at range you're still allowed the benefit of soak, but not when you're facing off against melee weapons--many of which have things like Pierce and Breach.
I houseruled at this point that Parry and Reflect remove soak negating abilities when used. This really makes no difference when it comes to ranged attacks, because as I said, less ranged weapons have Breach or Pierce. It helped to make saber fights last a little longer at least.
Keep in mind that Melee/Lightsaber/Brawl only has one range band (engaged) compared to all ranged skills (and gunnery) that can have potencial access for up to 5 range bands, including engaged. This change would effectively neuter melee combatants entirely, pretty much nagating one of their only meaningful advantages for such a style (others being that generally melee weapons, aside from Lightsabers are unrestricted and the other being crit heavy and possible to take huge ranks in vicious, something that certain ranged bands can do pretty well.).
Of course, if it's a campiagn heavily centred around such conflicts, thats cool. But otherwise I would expect the entire group to favour ranged weapons that are generally capable of dealing greater damage over the same length of time and have greater tactical flexability. Though if that works for your group, fantastic!
On a different note:
Personally, I heavily lean towards the climatic side of things in the sense that unless the Hero was involved in an intense "kill them all" style of fight (e.g. The kind of combat that you would have when not attempting to achieve some other objective, such as escaping chasing imperials). I would probably handwave it as "Make a Lightsaber or Coordination check as full round action and if you succeed you impressively ward them off." Otherwise if you were fighting in an intense battle with the objective of either breaking through or dealing with an advesary, I would expect you to parry/reflect to show that his very intense concentrated enviroment will take it's toll on you. As a DM, unless he was the only character to step out, I wouldn't focus fire him down as it wouldn't be fair and I would assume that other members of the party would actively be doing things that would prevent the stormtroopers from simply brushing them off as a threat. If they don't? Well to be honest theres a limit to what even a Jedi can do and even they cannot deflect a barrage of bolts indefinately.
Otherwise I see wounds and strain as a themeatic rather then a physical resource. "Why would parry deal me damage?" Because your getting worn down by constantly blocking and even with all the training in the world, you still need a sangificant investment (in body as well as spirit) in order to beat off attacks effortlessly though ranks in Parry and Reflect are decent it isn't going to turn you into an absolute combat monster without additional investment, and the ability to pick the fights well.
Even if your ranks in Lightsaber can allow you to use other skills, in order to be a frontliner you really should have at least a passing consideration towards brawn, protect and other such traits to allow you to better take those hits. If you want to be a prequil Jedi knocking away shots left right and center, you better take your physical (Brawn) and mental (Willpower) condictioning seriously and actually commit to the concept, it's fully doable for a beginner character to be really formidable in that sense. If your a sagey type like Obi-Wan from the old trilogy, then stealth and careful uses of the force are your friends with direct saber combat being a last resort/a calculated action against reasonable odds.
Just picking ranks in Parry alone isn't going to make you invinciable, just with the correct training and vs certain weapons (lightsabers) it will improve your ability to take shots even more effectively. It's like my emerging force senstive character has around 400/500 exp invested in him but because his force senstivity has only recently emerged and that his defences haven't been properly built up (he a gadgeteer/stealth character by trade) even though he can throw out a ton of red dice through two ranks of dodge, a rank in defensive stance by maxing out the defence side of the sense tree, Tobin still needs to learn much more about formal combat before he is anywhere near as formidable as a Jedi from the movies (no ranks in parry or protect, infact, he currently only has two pips and sense.). I am glad for this because it means that the Hero's journey can be built up slow, but epic! That even a Guardian that drops a ton of exp on deflecting and parrying isn't entirely invinciable in the early stages of the game.
