With the new update it seems shards donations will be needed again until all the upgrades will be done…
Are those shards needed?
The obvious answer is YES: You need those shards to upgrade MOXIE to the max (Deployed heroes will take 20% less DMG at lvl 5). You also need to upgrade TREASURY so that it will increase the spawn rate of rarer Guild Chests (lvl 3 Guild Chests can contain FAME)
So, as you see, upgrading these is absolutely necessary.
Upgrade as soon as possible to remain a competitive guild.
