bigger playerbase = more fluent ingame eco = more possibilites
and i dont know when ive seen Shield(!) IV the last time on sale, its been a while.
Shield was on sale like once half a year but the sales are identical so ... some people should maybe open their eyes? And it was Shield IV so you'd need Advance IV to make Recon IV out of it. Yes, IV. Not IX like a lot on US have. (thats 3125 IVs for a single IX ...)
Legal IX / X Recon on EU are rare as a snowflake in hell , still i've seen people on US complain a lot that "we need Recon X sales now because its impossible to keep aggro". I obviously got flamed for L2P
Fun point: 100 EUR = 3000 diamonds EU , 100 EUR = 4500 diamonds US . Prices in Diamonds for Shopitems EU=US. Some exceptions to the pricing rule may exist but its been a looong time since ive seen actual examples of it
But some people just like to find excuses. Age old discussion that goes back to maybe somewhere within the first 100 posts of me in this forum and even earlier.
US and AU bascially did whatever the f... they want back in the day. +16 stones on US weeks earlier than the rest of the world? sure, no problem. The actual good weapon runes as tier7+ sale for cheap? no problem, just took another month or two with different but crappy rune sales inbetween on EU.
Recon X on AU for almost nothing? sure. Great Golden Repair hammers in a big pack equallying 8$ but 20€ ? suure, why not. lol. (I complained about that with the GGR in the past and was told that this is not a bug

)
etc etc. but all of that is 1,5+ years ago.

The mount is a collectors item, really. The usefulness is somewhere around ... zero. Yeah, 6 players. Last time i tested it ran like ..., dropped people off, people were ported to starting location or started randomly dying while mounted(!) ... and its loud as freaking hell with annoying sound.
If you have 600 diamonds (~18$ off the biggest package w/o diamond sale) and are one of those "I dont have that in my collection yet" - go ahead. I could have gotten it from my Scoreformore Points on EU and didn't. I just got me other stuff and in the end gifted away some stuff from some of my points. But for actual usefulness? Well, idk ...
