Ah, so all cores are purchased with tokens.
The downside to the common token method, someone wants a nice Reklar item, only has to hunt Reklar once, get the plague essence, hunts sog 10 times, done, make a Reklar Sash.
I still believe there should have been separate token types for each boss. Those tokens buy that bosses' forms and cores only. For the lesser bosses, the token reward type could be easily made random, by instead of dropping the tokens directly, the quest dropped a "Token cache" container, which you open and it rewards a random token type, in a preset or random amount. Use the "present, coin bag" tech the game already has, is already using to drop the taravist crystals, annisil cords, etc.
Then the precentages I mentioned above wouldn't be needed, but you would have to still hunt Reklar to get his forms and items, but using the spread among all participants method (this new method, which I really like).
The biggest change I can see is you might need a couple more npc's to double as vendors for the different token types (not difficult to implement at all, just use the other outpost npc's. Vargas can remain the quest giver npc.).
*************
On a side note, many of my guildies are expressing huge dissatisfaction over the amount of tokens compensated for the existing forms. One said she paid 5g for one form only to get 24 tokens, or 1/12th it's replacement cost as re-imbursement? Needless to say she is having a bad week. Players who already had the forms have put in many hours and coin to get those. A more fair re-imbursement amount would have been 144 for each formula.
For new players, I suppose the amounts are ok, and it will take them many months to complete the formula collection (at the expense of buying the cores). That was probably intended and I think is ok, but we already have put in years of work, the re-imbursement amount needs re-thought. Even at 288 tokens re-imbursement amount, the players who had all the forms will STILL have a lot of work to do collecting tokens for forms, becuase there are so many new forms (7 for sog, 1 for queen, thats 2304 right there, plus the processing forms to go along with 4x72 for bipeds is yet another 288, 2592 total still needed, even if we had a 288 tokens per old formula re-imbursement). Please re-visit this.
If there are records of the forms that got re-imbursed, now would be the time to split the tokens into 4 types (1 for each boss), and even the new generic cores could be swapped out for the varying types using the same method that replaced them to begin with.
