4 million gp is a joke and insult to all the players who have been slogging it through intermediate mode for over a year. Fundamentally they seem to think that people play conquest for fun and not for the shards. The rewards at every level are poor, people play and suffer for the shards nothing else.
I've done 2 conquests in hard mode - knowing I'll get close to unlock makes it so much more worth while. For those below 4mil, having 4 characters unfinished and no way of finishing them is demoralising.
The argument that we're not meant to have them until you get to 4mil is irrelevant because the further you are away from 4mil GP will reflect the amount of shards you will have and therefore the amount of time it will take you to catch up. For example if you're a 2mil account in all likelihood will have a lot less shards accumulated then if you're a 3.5 or 4mil GP. The aim should be to enable all players start that journey of catch up to prepare you for when you are ready.
