mw's wont be any more boring than hw's and will they be anymore exciting?????? i doubt it for a while, hw's are great but all i ever seem to see on youtube is flippers (yawn). (flippers are great but their are too many)
i think you would end up with more mw's than hw's, which could lead to sum great robots being built and possibley evolve like the fw's, the main reason most would probably build one is they are easier to transport. When i took my hw to one event i had to take it through a door sideways!! its scratched the crap out of my car, and wasnt vary easy to secure in the car,
it was a nightmare..
Even though their is no easy answer, i think the biggest problem is its not full combat which is also not do-able with mw's but at least their would be more robots.
People might moan about spinners detroying their robots or causing too much damage, but im sure with all your hardox you would be fine, and yes i know the cost of a full conbat hw arena isnt doable, im just saying what i think the problem is, before anyone starts kicking off.
Hw's are what people will always want to see because of their size, but to me its like boxing

what would you rather watch danny williams,audley harrison cuddling then throwing one big punch and its all over.
.

or would you rather watch amir khan, ricky hatton?

totally agree a revamp of the rules is needed on robots, lifting a hw robot into the arena for it to get flipped out after 20 seconds would annoy the crap out of me, and also it would if i was a audiance member waiting for the robots to be brought in, armed, etc.... then to see it just get thrown out...

i also think a mw is an easier step up from fw's.
