The Legion Shop follows a weekly limit system where the items have weekly purchase limit that resets on Monday. This restricts how much one can grind with the limited coupons and slows gear progression especially in Reg Server. I am hoping in the future, KMS can lift the purchase limits of items so one can buy limitless amounts of an item assuming they got all the coins needed. Here are some examples of change I hope see as a result of allowing us to buy without a weekly limit. Please note this from a Reg Server player so some stuff might not make sense to a Reboot player.
Legion Might/Wealth/Luck/Expertise: With 20 of each 10, 20 and 30 minute buff, we are given up to 20 hours of pure buff goodness. Lifting the limit would allow us grind with boosted rates more per week since we aren't limited on 20 hours. Another bonus is we would not have to buy 20 or 10 minutes and can just buy 30 minute coupons online so it better matches our WAP and other EXP buffs since those are 30 minutes or 2 hours. And in most cases, a 30 minute coupon is actually cheaper than buying 3 10 minutes or adding a 20 minute and a 10 minute coupon. By lifting purchase limits, players can train more, better manage buffs by durations and spend less Legion Coins due to not needing to buy 20 or 10 minutes.
Legion's Honor EXP Guarantee: This just turns 5,000 of our Honor EXP into a medal to be sold or passed to another character. Makes no sense why only 3 are allowed per world. Removing the purchase limit would be beneficial as it allow players to extract more than 15k EXP week. A great use is for those players who finished all 3 presets and want to drain out their Honor EXP as fast as possible for their alts or sell into the market since Honor is no longer needed for them.
Enhancement Items (Karma): Karma Enhancement Items can only be used on untradeable items. The Legion Shop has Hard Cubes, Powerful, Eternal and Black Flames, but they are all in Karma form so they can only be used on untradeable items. These items have a higher purchase limit, but this is World limit shared among your characters in the same world. 30 Solids, 20 of each Powerful and Eternal and 40 Blacks are your limits. Removing the limit allows us to go on larger flaming sprees (cubing to unique exists but IDEALLY you want Legendary before you start looking for the 3Ls you want.)
Enhancement Items: We are given 3 Clean Slates, 2 Epic Potential Scrolls, 3 Potential Stamps, 3 Powerful Flames and 2 Bonus Potential Scrolls per week per character. This limit can be bypassed by passing the item you want to enhance through storage and visiting all the characters until you are satisfied with the result. This loophole is tedious and can be annoying to your buddy list and alliance(s)/guild(s) if you are logging in and out of 20+ items to reflame or Clean Slate an item during Spell Trace Fever.
Giving us unlimited purchase limit allows players to Potential, Stamp, Flame and clean out failures all on the same character without passing gear around. This not only works well not only on New Projects like unworn items that could still be pass around through the account, this works extremely well on items that already worn. New players, inexperienced players or those who just rush just equip any new item CLEAN without any enhancements. By wearing an item early, the item usually becomes bound to that player and it becomes no longer eligible to be passed around the account and that player can only enhance with the limited weekly per character limit. Unlimited purchases gives the player the ability to buy as many Clean Slates or any other enhancement item as they need without worrying about wearing an item too early and making it impossible to pass through the account.
As mentioned mentioned in the previous bullet point, Karma enhancement items can only be used on untradeable items. Lifting the purchase limit gives those who already untradeable items the same edge as those passing items through their account. It could get to the point that equipping an item early to make it untradeable would become favorable than using the pass it through the account until it ready method. Currently, if you were to equip something early, you limit the number of enhancement items it can receiving since you cannot have your legion alts help out while opening the item up the ablity to Karma Flames and Karma Cubes. However, if both Karma and its regular version of the enhancement items had unlimited purchases, equipping an items grants you access to Karma Flames and Karma Hard Cubes without losing the benefit of fast access to Clean Slates and other limit per character items.
