It's a rather easy contradiction of his statement.
Breaking it down simply:
He see's something and then creates a generalization based on what he's "seen" in HIS personal experience and calls upon that purely as a global truth to fit his argument. When the fact remains that many players can flawless/minimal loss rush warden tower bases, just because he hasn't seen it, doesn't mean it doesn't exist, because it very much does!
It all applies to the correlation of David rushing being more dominant at higher levels than lower levels, which implores questioning the decision of allowing a L60 in wood III, to get 5 pts rushing while a L20 gets 1 and has less bases to consume for said pts making it near impossible to catch up.
Each side of the argument could also be flipped, L30 David rusher vs L60 no david rusher, L60 rusher vs L30 newbie. The only way to truely fix the issue IMO, is completely segregating leagues by level and/or unstacking David's abilities.
Willfully ignoring objectivity because of personal bias (he got what works best for him, therefore it's good for all in his eyes) thus he can't see anything wrong with the update, and sits in the realm of willful ignorance.
My 64 loves the update, my 33 w/92 pt lead, was just jumped by a 59. I can see both sides, he can't.
never offended my friend, you too.
