It's not all that horrible tho if you take into account that HxH chapters are usually rather packed.
There are many shonen's in which nothing much happens in one chapter, exspecially in transition chapters.
People talk a bit, maybe a joke and then peple go to another place or a fight is set up.
Judging from the 9 chapters we got last time we get a lot of information per chapter
So, at least we get some progress when there actually are chapters.
It is much worse with berserk. There is one chapter every few months or years. A good chapter, but nonetheless.
We got a tankubon 2011, then one 2013 and the next one will definitely not be out before 2016, and the tankubon consists out of 9 chapters.
With HxH, i do not have to doubt that Togashi will finish it that much. He works, in his strange way, consistently and the chapters come in blocks, so at leaser there is something to read without forgetting what actually happened between one chapter and the last.
