Well,
Until Mazda farms out the cranks to Jethro's aluminum siding and crankshafts, the Rotary will remain the winner just from the factory not screwing them up.
 
And it is always the company trying to make more money. They are more than willing to bet your life that they can get away with some new gag to save a penny. If you can get $20,000.00 a copy, maybe that can last a while. Not the case in car engines.
 
There seems to be a gap in the engine support systems area that needs work. Not to put too fine a point on it......................A piston engine can survive for years with no air cleaner. It can survive ingesting a broad selection of crap and keep right on going.
 
The rotary can do none of this. All air has some abrasives in it. The apex seals are moving at the speed of light. It takes just a small obstruction to damage a seal. The addition of an air filter is as basic to safety as the seat belts.
 
The filter is to remove the abrasives and evil spirits from the air. None of the installation counts for anything if a piece of the filter housing, cracked ducting, sealant, brackets, assembly fasteners, or even a fragment of hardened Locktite, is available inside that system, It will eventually go through, (or more correctly, part of the way through) the rotary.  
 
I don't think this type of situation should count against the rotary. If there were some malady that kept biting every installation that was engine based, then there would be some engineering operation to address that problem. But I see none.
 
You cannot pound out the center main bearing saddle. You cannot swallow a valve head. You cannot break the crank. You cannot crack a head. You cannot shock cool a cylinder. You cannot wipe off a cam lobe. And you can lean it until it stops without melting anything. 
I was going to add that you cannot over-rev it, but with no prop and no rev limiter??????????
And if you do hose it up so bad it stops, it is unlikely that 8 quarts of flaming oil will blacken the windscreen. Notice the "Nearest" button actually vanish from the GPS when this happens.
 
But I run on as usual.
