You get some resources back and a new shiny set released to keep things fresh. Just invest the resources you organically drop and there is no issue of wasting extra effort.
Also, view this as an investment aimed at yielding short term rewards, such as tilting the balance in TW and GAC and winning more often for the duration. Prioritise the level of resources you want to allocate for that in comparison to longer term investments like unlocking and levelling characters.
20% back of what you put in means there's actually a fair bit of wasted extra effort.
