Wait, so according to 3 DST, BC and WC are "p2w" dungeons... but the only thing stopping you from dyads (that cost 10k for to fuse the squares into a dyad before even taking into account any of the lower transmutes / smashing gems together) is because you don't have enough hexa's you can buy with powder? Thats more than enough to buy the gear to enter WC... so does that make you a full p2w player while crying game is "p2w"?
------------
1) You do not craft non-tradeable oils, you can only craft / transmute the tradeable version and the main cost of that is Evolved stones and Transformation stones making up 80-90% of the cost (if you buy the tradeable mats to make crystals) so they would need to add something else to the transmute (also tradeable) and risk boosting the price of it and everything else in the process and making PTS even more expensive overall...
2) The boxes are fine, all changing it will do is make higher geared people recruit more multi-runs with other higher geared players (giving them more mats) resulting in lower gear players crying that it can be cleared with less gear (while refusing to run it with people there own gear) and blaming the higher gear for making it "impossable" to farm because they are to lazy to farm it without high-gear carries dragging them along.
3) As already mentioned the merchant was a temporary event and then they nerfed it when they brought him back to stay, and again on lower tier dungeons they would still want higher gear to make the runs faster or they would simply solo it because alot of the lower dungeons are faster to solo than wait on other players in loading screens. This means that again people would complain the higher gear would carry them along while they refuse to do it without them for no reason other than they are to lazy.
4) I have no idea how it works with the file size, so no comment on that one.
5) You clearly have no idea how the market or supply and demand works in general so just going to ignore this.
6) Your quiting the game because you have really low gear (calling dst, bc, wc pay to win dungeons) and they are blocking you from spending tens of thousands of gold on gem powder for gems that will give you a fraction of the damage boost gear upgrades would give you... That has to be the dumbest thing i've saw in this game, cya.
7) In other words you have purples stones from daily 5/5 or weekly 5/5 + possable orange stone(s) on alt characters that you would rather have on your main, that is the reason they are not account bound because then people would cry that others get them faster because they do dailies on 11 chars to get 11 boxes / free stones each day + 11 more per week (so 88 chances at legendary stones / week).
