well to play devils advocate

if you sink all that money in the first few days even weeks of server

You could then save all the gems you would use to clear cool downs
use the perks form vip 11 and 12
never need to open extra cues
and have a ton more gems to use on opening chip slots and buying gems and cards and stars
and paying 100 gems every time you saint etc

SO there is a point to it i think, but only if you hit vip 11 and 12 very early in a server.

But if you gradually over the course of many months upgrade to vip 11 and 12 the perks for those levels become pointless.
