Why in the name of all that is holy would you want them to revert this change? It makes it to where the whole continent is relevant rather then useless. With gear you will be able to destroy the mobs out in the world with ease after a time as if they were multiple levels below you. We get to go to any single zone and quest even if just for gear or artifact power instead of being pushed into one single zone like is typical.
It used to be really easy to get dazed back in the day so I wouldn't complain, lol

After time what takes 5 days will only take 1 so your alts will be able to catch up quickly. You may be 1-2% behind your main but never obsolete.
