okay, i will try to explain it in very simple terms:

the whole idea behind tiers is to make it as transparent as it could be and as much specific as possible based of "improv and comebacks" approach, so any freshblood who decided to be a part of team wushu knew what exacly expected from him. or person who want to evaluate how good he really is can check out just by reading requirements.

and based on tiers requirement he would know what he need to work on to become one of the best members of wushu cult.

it's not about who is better or worse, surprisingly, it's about promoting sportsmanship (comeback all the time, improv)

removing specific requirements or making it vague can turn it all into popularity contest

"i wus bettur, i made mor for shushu then you etc" that kind of shit.

i'm all for updating tiers, as long as it will be objective, clear and not dependant on subjective factors as people's opinions and current state of wushu.

if you are best among current wushu players but objectively you are very weak t3, then you should be t3. it will just mean that everyone else is not even on t3.

we all want to feel like we are awesome, that we are legends, that we contributed alot, but it's ignorant. if i suck today, i should stay in tier i fit in, no matter what i did in past and no matter how good (not) i was.

objective requirements that don't depend on people's opinions is what should be worked on. as much specific as it possible.

offtop: if we are really talking about people who changed wushu, it was clan [impro] and it's members. no contest here. just a fact.
