'Official' servers are for people who have no issue taking weeks to build & hours to tame. Boosted servers (dedicated) are for people that have lives away from their Xbox consoles. You can set all the stats the way you want them. (On my server, it only takes a fraction of the time to tame compared to official, 25 mins for a prime 140 Rex).
I have respect for people who play on official & can get up and going, but I work 12 hrs a day & don't have the time to put into official.
