Those who only play the English version won't be able to speak on behalf of the original version without consciously leaving out information that makes the latter special in its own right. I hate to break it to you, but you're mistaken on that part. You might not know that many of those free flower stones actually don't come from just compensation but rather from special login campaigns coinciding with events (including festivals unique to the Japanese, as well as player milestones --- currently, devs are giving another 20 flower stones over 10 days for the 1,450,000 FKG players milestone), on top of the regular 10-day login bonuses, so you'll get an additional 20 to 50 gems within 2 weeks depending on the occasion... and I'd like to add there are other campaigns ranging from 30% stamina discounts on various maps for certain days or weeks, 2.0x gold campaigns, and campaigns that increase the experience from leveling knights and "great success" from upgrading equipment.
If you'll be talking about "everything available on DMM," you might as well take note of the abovementioned things as well. Yes, it is imperative for the devs on Nutaku to eventually add more of the features essential to gameplay on the English version, but the stuff that make the Japanese version unique (and better by a mile imo) is something the other version can't ever have simply because the devs behind the latter are not THE Japanese devs.
