Not contradicting: my argument is not for a complete ban of certain power categories; rather, for the degree of regulation. 

Disparity is okay up untill the moment you find yourself unable to anyhow interact with your opponent's attacks other than take damage, which is seldom an entertaining thing. Dodge, block, constantly outmaneouver and stay out of their effective range - one should still be able to deal with the majority of their opponent's kit with the baseline tools, taking crippling punishment for being unable to effectively utilize the options at their disposal, not for lacking a specific option.

Shoving someone around with shockwaves out of a limited resource pool is fine; as is taking potshots at someone with a two-shot gun that'll bruise, or heavily injure only if it hits a vital point. Both have the potential to end a fight on their own, but under specific circumstances, which makes it the wielder's job to work for the kill, not the recepient's worry about having the right tool to avoid an otherwise looming doom.

Combining heavy damage with a innate requirement for additional defenses - meaning it's unreasonable to expect any conventional means of defense to worl, such as dodging - is a recipie for salt. I don't want to be burnt to a toasty crisp just because i had no faraday cage on my face, or have said face blown off by a gauss gun (which is assume is far beyond the realm of convetional firearms in terms of projectile speed) because my character isn't tougher than a battleship.

I may be misinterpreting the actual reality of this tournament's character balancing system; but then again, i feel like a Mitsu Vs Mitsu mirror match would be just like one of those wild west cowboy duels: whomever draws first and nails the other with a shot is the winner.

EDIT: this is all a purely theoretical debate, to remind everyone. I wont be able to participate for unrelated reasons regardless. Be civil, be nice, know when to abandon ship.

EDIT 2: i'm not assuming that you're completely oblivious to uch concerns or the like; rather, i am simply stating my stance and expressing my doubts reagrding the actual implementation of the concept and, most importantly, its sufficiency, to elaborate on my statement in the beggining of this post.
