My predictions :
1. Titanium Hammers will be removed from daily loyalty bonus (since they are on "Promo" in IS sometimes - just few hundred dias for 60-75% failrate)
2. +20 Jewels will be removed and replaced with +30 jewels instead which cost like 1/5th of the +20s in dias.
Double ruby bonus is a nice idea, but still doesn't cover the massive deficit of rubies on servers.
16 pieces of gear = 16x 4-slot drillers.
16 pieces of gear = 16x perfect +6 jewels (if you don't use the dia jewels to 6 which seems almost impossible lately. 30-40 jewels for 1 item. My best is dropping from +5 to +4 15 times on 1 item).
How many dias needed to get that many rubies? I can't be bothered to work it out, but it is a ridiculous number. Not to consider any other gear you are making too, such as PvP gear. Or like others have been saying for years, put the items that are only in the ruby shop also in the normal IS.
