I think the reason is that ebonite/hammer hasn't made any breakthough material or anything that stands out from the rest. Like track has thier morpheus cores, and now the highly popular rev-lever in the rule, storm has the RAD core, which had proven to be extremely popular, brunswick has thier activator cover, legends now has thier diamond particle which is getting them some attention, and so on. I just don't think that ebonite/hammer has had anything like this in the last few years or so...
