I think these changes are fine. I am in a guild that gets about 15th on trophies so there were 450 players in top 50 guilds gettings more resources than me.
My resources were directed towards new kingdoms and new mythics.
Leading into the latest mythic I had the following
12000 gems ( ~ 2.7 expected mythics)
1000 gem keys ( ~ 1 expected mythic)
4000 glory keys ( ~ 0.4 expected mythic)
40k seals ( ~ 2 expected mythic)
With crafting coming there would be no tension in my use of free resources. I also at one point was down seven mythics so I had caught up on them and am now only missing 2.
Basically top end guilds were and probably still are getting too many reaources.
This will force people to chose more carefully what to spend gems on. This is good there is now tension between using gems on VIP vs crafting
I think that is good
It is a game after all and you do not want it being to easy.
PS the point about VIPs getting burnt is relevant and the devs should consider allowing crafting of VIP keys. Ie 5 gem keys / 10 diamonds for a VIP key
