Well, I get what you are saying, but I still know the fastest strategy to get to 80 on the whole map using only the Ice Staff, which is to actually camp at the semtex in-between Gen 1 & 3, with both doors closed for extra fast spawn in's, then I will swap out to the wind from 80 onwards. Less than 2 minute rounds all through the 60-70's.
Fire Staff will cause the game to freeze up 90% of the time after 50, and lightning is useless from 35 onwards.
Basically, the only advantage to this is that you can hold the wind and ice at the same time, and unskilled players will not be able to train in tough spots like gen 4 or under the church, so they will opt for the safety of the crazy place, where there is actually NO advantage, as the staff holders are all there anyway, so like I said... they are at hand anyway.
I get that it will help "good" players make it from 80-100+ easily enough, but I would hardly consider it game breaking when only 2 staffs actually work beyond round 70. The worst thing about it will no doubt be the in-game trolls who try to grab as many as they can.
I won't ever be doing myself personally unless it becomes common practice throughout the community. People consider the hacker spitting trick on Moon to be a glitch, but everyone does it, and Treyarch never patched it on their final BO1 title update despite it being very well known.
