I've only dabbled in JKD, so take this anecdotal story for what it is.... One of my buddies was training at a BJJ school that also taught JKD. They didn't really allow any sparring, just drilling where they did allow contact, but always in a controlled form (only jabbing, only trapping, etc). After he had been taking it for a year we got to play around in my gym...
He was completely lost when he wasn't in a drill with clearly defined skill sets to be applied. My lateral movement and orthodox lead (left foot forward) had him confused, me changing ranges and mixing up my tactics with broken rythym had him completely frustrated. He wasn't able to deal with the improvization that comes into play with normal sparring. I was able to keep him outside of his comfort zone and simply dismantle him.
I was surprised because I had drilled with him before this and he had very sound skills, but he hadn't figured out how to apply them outside of drilling mode and how to apply them with someone not doing the same things. He said he felt like he was always a step behind... that he was trying to figure out what I was doing, then adapt to it while I had already moved onto something else.
I would ask your instructor about sparring, just be respectful and ask him if you could spar somewhat. Make it clear that you aren't trying to challenge anyone except yourself and that you aren't trying to hurt anyone.
As for contact levels, while going hard every once in a while is beneficial IMHO, I've always learned the most when going light with my partners (50-70%) power since I wasn't afraid of getting hurt, I could relax and try out new skillsets I wasn't as comfortable with instead of going back to my bread and butter techniques.
YMMV
i have only one major problem with sparing... people tend to dodge back a lot and get out of range...
in my experience in a street fight people are coming together (usually very fast) to hurt each other...
whilst sparing can teach you a lot its imo as important to train in more practical scenarios as well... not in drill format, completly free form but the interception element of jkd is imo improved with this style of training...
sounds to me your friend was learning jkd in a very haphazord way... trapping and punching are not seperate things... the ranges of combat are not static and drills should where possible move over multiple ranges... and to me drills should ALWAYS have multiple outcomes... say you oblieque kick then then may step back, may step off may shuffel back or may attack with hands... we never know what the reaction will be and then react to the reaction... it teaches distance and timing as well as making you think... also i hate training in gyms... matts just annoy me you dont bounce and move in real life like you do on matts and wooden floors let you move your feet in unrealistic ways... we train on concrete sometimes... uneven surfaces etc... that teaches you a LOT especially about footwork... pushing people over kerbs etc
imo i get more for street defence from that type of training than i do from sparing... though we occasionally spar with some mma guys in another class its just not very real to me... we cant take knees, throat shots, balls, eyes... all the good stuff is off limits...
not to dis sparing though i think its essential to help you be comfortable in your stance and find out what works for you and you have to know how to take a punch or several (though we do allow quite heavy contact with our drills especially for leg conditioning... ouch!!!!!)...
my own favourire is being well protected (headgaurd with face guard, hockey pads, groin protecter / belly guard for the kidneys, mma gloves)... then just go for it 100%... short and sharp both of you coming together cos thats how it happens in a street...
