Riot is ignoring what is needed to tune junglers since preseason before 7
There are a notable number of farm junglers. These junglers are farm types because of the way they have been tuned. There are junglers that have to rush to 6 to be effective, the solution for these junglers are relatively simple in that they need to have some power adjusted out of their ult and spread into their basic abilities.The other group that will need a much more drastic overhaul are junglers that are heavily gold reliant. Gold reliant junglers are the ones that are hurt the most since the plant preseason. Before these champs were able to sidestep the extreme gold need through the power of stacking jungle items like devourer (not saying that these types of items should return). For those farm junglers the options are either major kit overhauls that would be frankly on the level of a roster update, item tunings to lower their gold cost but that will have affects on the lanes of course if powerful items got cheaper champs hit powerspikes across the board much earlier. The last option that I would suggest that requires less large overhauls is to take poachers dirk and change it into something of a more dedicated jungle cull, an item more purely focused on the PvE playstyle. Simple idea is to increase the champs damage to monsters by x% and for the next set number of consumed stacks gain bonus gold, make the stacks consume one per camp on your side, 2 per scuttle, 3 per epic monster or counterjungle.
Though I highly doubt riot will take proper steps there is no way they can give responses of not being able to come up with solutions, and we can't as a community let them ignore the champs that have been having issues since 6.22 and have been continuing to have compounding issues caused by riots blind disregard.
