how do you change your fighting tactics to compensate for that?
To expand on what I said to you here
Fighting for your life has a completely different psychological impact than fighting in a safe controlled environment for pride and money.
Anyone who thinks theyre the same has never had to do the former.
Like kids who think they can take the psychological damage of combat because theyre "MMA/Boxing/wrestling badasses because theyre used to that type of pressure" or my personal favorite living in Appalachia, "I've killed living creatures, humans cant be that much different."
Nobody steps into the ring fearing for their life.
Machida and GSP knock folks out pretty frequently with it..Most folks (even the non karateka) have said many times on this forum now that how they strike without their grappling is exactly what youd see from a high level karateka.
Its still a hugely popular style in Kickboxing, I suppose kickboxers dont have good fighting ability because they dont grapple though.....
The argument was that ability to fight defines ones ability to defend themselves. Many, many jobs prove that wrong. Cops are just one.
Fighting isnt inherently a necessity to be able to defend oneself
No amount of regulated/sport fighting can prepare for the psychological impact of fearing for your life.
Getting used to contact helps
With that in mind:
I'd rather train in a school where when we drill our everyday SD/Bunkai, im working with someone twice my size whos swinging full speed right at my face. If I dont move, somethings getting broke or cut and it has been. If my positions off, I dont get the takedown because theres nearly a hundred pound difference in size and couldnt muscle the guy an inch.
The issue with weight classes is they dont get you used to facing an opponent considerably larger than you.
Where Im not told "These are all illegal moves, you cant strike here, here or here, this techs illegal unless youre in this position, etc." and I have full range of attacks and target areas Im allowed to strike.
Where in Free sparring, Im still going up against guys twice my side and have to learn how to adapt from that.
Where instead of training for a very specific ruleset in a 1 v1 match, we frequently mix it up and do 2 v 1, or punches only.
Where we drill, drill, drill full contact SD for a variety of situations. Grabs, intimidators, sitting positions, do bullpin sparring
I've had just as many injuries in my TSD training as I did when I was competing in Boxing and Wrestling.
Quite frankly, there is nothing an MMA gym could give me other than a bit of BJJ (which is on my bucket list assuming I can find a school that simply overpriced, commercialized egoism like the current ones in my area) that I cant get with how we train now. They could assimilate me to MMA rules and break habits I have that would get me DQ'd, but thats it.
Everything you could get for SD from MMA, I've gotten from TSD and wrestling. Many people get those things without ever stepping into the cage for a match.
Maybe in the early days of Vale Tudo and MMA, when dang near anything was allowed, it wouldve been a better fit for general SD. But where its at now, its so centralized around the rules of its own competition to be some "superior method"
When both methods use full contact, and neither can prepare you completely for the psychological impact of actually fighting for your life, I'm going to go with the one that doesnt limit what I can do from the start and gives me the most options.
