Bro don't you think getting Mythic Pack (from Daily ranking) as well as same overall ranking is getting tougher. You need 80,000 coins to enter Top 20 and by finishing all quest goals alone now does not ensure you to end up in Top 100.
One of the reason is that - now it has become easier to complete all goals - thanks to Colosseum event reward items/daily ranking coins.
I see a lot more players with level 15 Mythics, with Top 10 players reaching level 20 Mythics as well - Directly because of Mythic Packs as well as increased event reward (number of Mythic) at Top.
