What is the most profitable use of Season 3 and Season 4 map currencies? I have many stacks of Season 3 and 4 map currencies (north of 70), mostly obtained by completing WvW reward tracks. I've bought all of the nodes, minis, and ascended stuff that I need, and am wondering what to do with my leftovers. Do I simply march it,  or am I better off to convert it into volatile / unbound magic and buy shipments or packets/bundles?

Also, is there any tool out there that shows what the best use of the currencies are based on TP prices? TIA.
