makes no sense to me whatsoever. this game is getting too confusing
oh its quite simple really. There is a new episode coming out in around 3-6 months and the lvl cap is going to be raised to 80 (most likely, not really confirmed). Players at the moment are getting close to finishing their 70 gear and have spend a bucket load of money on linking, enchanting, orange stats and what not. When ep 5 came out (the episode we are currently in) players old gear (goddess) suddently turned worthless (this was before goddess pvp map and token farming) as the new quest gear (and even more so the farmed gear) was a HEAP better than their old gear.
So players are worried that this will happen again and all of their hard earned money that they have spent on ROTCO/70 AP gear will be wasted. So tactics and his team decided to release tokens that allow you to change your current gear into the new ep gear when it finally comes out. To get these tokens you need to spend some AP. The first token 'S' was tacked onto the end of a 15k tier event, only costing 1 extra ap. Since then it has gotten progressively more expensive, from an extra 10k at rebate time, to being one option in the 25k tier! As well as the 'S' there is also a 'H' and an 'I' token. these are all for different items. It was always just an optional bonus for those AP spenders that wished to gain some of the new set as soon as the new ep is released.
Then Tactics and his team apperently listened to the QQing of the community (or possibly they had planned it all along .. but thats me guessing) and they decided to help out by letting you get some more placeholders that will keep some of the lapis linked and some of the enchants. yes, thats right, more placeholders. So now you get options in 'mini' tiers to spend 15k to get a placeholder called Troll of a Tear C. So now you have purchased the 25k tier to get your letter H, and you have purchased a 15K tier to get your Troll of a Tear C which lets you transfer the enchants from your ROTCO gear to the new gear that you get with the H but minus . So if your rotco top is  and you use the H placeholder to get 70+ gear and you have the placeholder Troll of a Tear C then your new 70+ gear will be . that is crap you say? well you have another option. If you do the 12.5K option of that tier then you can get a mystery box that has a chance to give you Troll of a Tear C2. This means that when you have your placeholder H which changes over an item of ROTCO/70 gear to an item of 70+ gear you can also use your placeholder Troll of a Tear C2 and this is only a minus . So your  enchant will be transfered as a  when you get your new 70+ gear.
Phew, after all that you have one clean new 70+ gear with some enchants. now, you ask, what about my lapis?! well Tactics has you covered there. all you need is a Tear of troll B2 or a Tear of troll B3. these will be released in much the same way as the enchant ones i assume. with the lower one being released in high lvl tiers and the better one being released in mystery boxes. Anyway, if you manage to get your little hands onto Troll of a Tear B3 then you can transfer 4 lapis from your 70/ROTCO gear to the new gear that you get with your S H I placeholders. But if you only get a Troll of Tear B2 then you can only transfer over 2 lapis from your current gear to the new gear.
See i told you it was simple.
