I tend to state this in business terms (too much time spent as a consultant) - it's all about risk-reward analysis.It’s all about analysis IMO. Nothing you do is going to be 100% effective and zero risk. Move one way, you open up targets. Move the opposite way, there’s some new one. Don’t do anything, and you’ve got other open targets.
The analysis will show what’s open and what’s not. With this stuff, it’s picking your poison. Everything’s a trade-off. It’s a balance between protecting, attacking, and being mobile enough. And every opponent is going to change those priorities and force you to compensate for any of those aspects; a faster fighter vs a stronger fighter vs long reach fighter vs...
It’s all about trade offs. Least harm done to you and all that.
