I've worked on a lot of large networks and when you get into specialized requirements (like running an MMO or MOBA) things get a bit oddball. Companies like Cisco make generic equipment that do generic things, some of it is specialized, but they are made to sell on quantities because making a product for only a few vendors would be idiotic.
This is why companies like Blizzard, Amazon and Google make design a lot of their own stuff or take a product and heavily modify it. Fixing this stuff isn't as easy as "hey, just buy some new stuff and hook it up".
This isn't your computer running out of space because you download too much porn and you just need a bigger drive. Unless your in the industry and know about this stuff, you should just trust they are doing their best.
