These changes dont address the problem with heroes lagging behind. Sure you can max out a th9 or th10 super fast now but your going to either:
1. Have low level heroes when your village is maxed otherwise.
2. Waste hundreads of millions of resources waiting for heroes to finish before advancing.
The reduction in time just helps rushers rush faster. With CoC being a strategy game, it encourages people to play the game poorly in respect to village advancement compared to practical hero advancement. If one doesn't know why hero levels are important compared to village development, disregard everything you just read.
