Yeaaa i guess i kinda get it but if someone dosent need 2 extra stam like myself then the helmet seems more valuble but its all opinions because the least id sell this helm for would be 40 mil but it fights my suit perfectly so i wouldnt take 40 mil. Thanks fellas.
the main reason the 2 extra stam matters is because you need it for 210 stamina suits, which is the only way to reach max speed with a composite bow.
as for effecting the price, look at it this way.
an imbued 8 stam piece is worthless. basically the cost of imbue mats
the only way to get 10 stam is reforge, or loot. just a clean 10 stam mod peice is worth on average 20m if it can be imbued to max imbue weight with no junk mods like lrc, stam regen, etc.
So the same overall weight, but one is worthless, one is worth 20m is a big difference.
When you get to 10 stams, theres so many pieces, so much supply for under 500 imbue weight reforged or loot 10 stams that cost is driven way down. like you may get 10-20 peices with 8lmc 3mr 10stam 4dstat for every 8lmc 3mr 10stam 8mana 4stat piece. so its not just how good a piece is either, but how easy it is to get certain stat combos.
I agree its a good piece, but the price comes down to supply / demand. the supply for 8 stam is much much higher than 10 stam, which is why on average a 10 stam piece is worth about 5-10 times more than its exact counterpart in 8 stam version (say if an items total stats added up to exactly the same, but one had 10 mana and one had 10 stam, the 10 stam one will always be worth around 5-10 times more.
Its got about 521 usable weight not counting stam regen (i never count stam regen in wieght because suits always have more than enough of it) and the 1 low resist means you need 2 artifact pieces in the suit.
So basically just a little better than imbued, but has stam regen and resists. on a luna vendor you may get the 40m, or even here if it works out extremely well for someone. I like the piece, but just do not really need it. would buy for around 10-15m just to upgrade an off-shard event archer or something, but no immediate need so a higher value isnt warranted for me. The lmc is a big issue too. its a little hard to fit in, rather than using 5 8lmc peices, or a higher cost 10lmc to allow for a lower cost 6. I use a 4 lmc piece in my suit too, but got it for about half the cost of what it would be if it had 8 lmc.
Anyway sorry for the long post, its a nice piece just explaining what goes into pricing a bit.
