let me try, you're right we get a lot of silver abilities from boxes, but u need to focus an eye on the abilities you get the xp cards for. There are 4 normal different categories of abilities. Gold Purple Yellow Silver .. Depending on the category, these abilities have to level up with matching xp cards .. depending on the category these abilities have strong or weak xp cards to level up.. for some you can use gold purple yellow and gray xp cards to level them up ,some for example only yellow and silver, and some have only weak gray cards to level 8 6 4 2 xp.. these weak abilities.. with 8 6 4 2 xp cards are really rare ,and used by a lot of fighters. these abilities are hard to level up. As an example, keep an eye on these abilities ..'''Power Uppercut..Teap kick body .. body knee .. rounhouse kick body .. or guillotine guard .. submission escape '''.. there are few more. compare these skills with others and you will notice that you will get much less xp cards for these abilities .. maybe 1-5 xp cards for the power uppercut per 100000 silver coins (say maximum 10) but 10 that is for my experience wishful thinking :) .... (rare. less xp. and used by many fighters)  that's why we say they're expensive .. pay attention and better only give these abilities to fighters you want to maximize... i hope you can understand better now
