I had such high hopes for this, but it just keeps getting Better and better
its about to end right? since there is no more material left to animate

After ant arc it's just healing Gon and voting for president. But recently the episodes have gotten so full of explanations and nothing else, maybe they want to stretch things out until Togashi gets over his crippling chronic disease.
There are rumours Togashi has given up on the manga and will instead spearhead the anime once it gets to the end of the election arc. I heard these rumours found their basis in /a/.
