A few Blade And Soul feedback suggestions

During the last 3 CBT i have come across a couple of issues while leveling. Now this is just my personal opinion so no flaming please.
1. Unsealing charms: These either need to drop much more frequently, need quantity in shop to be increased per purchase(5-10 for 10 silver), crafting them needs to be much faster(12 hours for 1 craft...), or even just offer them on the Hongmoon store(untradeable of course). Too many times i get blue Soul Shields from running instances and I auto salvage due to not having enough bns gold charms to unseal them. I really noticed this becoming an issue around Tomb of Exiles when it takes 2-3 charms to unseal a single soul shield. And even dailies were not giving these out for me....
2. Reward chests from doing dailies and solo instance quests, i.e. Viridian Chest: I am sorry but these are total crap. Not once have i seen anything from these other than a potion or repair tool. At least make these give a key or unsealing charm. I think i would have a stroke if i ever saw the brilliant key or venture tokens actually come out of one of these.
3. Poor RNG: I had the misfortune of trying to get my summoner staff and 1 certain soul shield from Blackram Narrows. It took me 24 runs to get the staff, which is 48 chances from boss drop and personal reward chest, and a total of 32 runs, 64 total chances, to get the soul shield www.bladeandsoulgolds.net number 6. Now the weapon won't be an issue for NC coin spenders buying keys from the shop but the soul shield... that was frustrating as hell. Likely this will stay the same since RNG is RNG and i have no idea what to do to alleviate it.
4. Weapon upgrade costs: These start out very friendly and then by the time you get to Moonwater Plains areas they ramp up insanely high. These need to be smoothed out a bit instead of going from a couple silver to get exp to 20+ per Blade And Soul item and that is not even mentioning the fact that the breakthrough in that area goes up to 2g+ per item. I think the overall cost should remain the same but be smoothed out a bit so it is not buy bns gold so much of a shock when you get your Blade And Soul items leveled and see that massive increase to price.
