We do not need more currencies in the game (SP/HSP)
this not only makes the future a nightmare of confusion for everybody
it also makes the refund concept completely unfair in far to many cases
many management styles were encouraged under the old system and the current refund proposal is harmful in many situations
This is my proposal
We condense all prior currencies into similar pools and expand their use
this allows a full refund all purchases relating to the old system
modules, consumables, provide their Cbill or MC cost
skills, mech XP and mech unlocks are gathered into a single XP pool
(that means individual mechs no longer hold any historical XP and future mechs gain no individual XP either)
All consumables and modules are refunded
ALL forms of experience are refunded and merged into a single XP pool

This will allow a cleanup of the skill purchase interface and allow players to focus on skill choices instead of be bamboozled by confusing options and conversion rates
It will also allow ALL players to have their total worth of play time, experience and expenditure refunded and be usable in the new system
all older styles of inventory management will transfer with equality to the new system

with out the need for excessive new cost conversion systems a clean and precise interface can we provided
space can instead be used to show players when they will need to purchase nodes or not
When the player confirms a selection they will be presented with a purchase window similar
with the option to pay with what ever currency you wish is open to all
(note that if no new nodes are selected this screen would not be seen)

The numbers are random and only to give the idea
But this would allow skills to be purchased for any mech from ANY available resource
players at any stage of the game will not have their time or purchases devalued
regardless of previous management styles, you will get back exactly what you put in
this would also open the door for spending in new ways for future content
