So even though jungle tanks tend to be in a sorry state in comparison to their bruiser brethren, I still enjoy playing them and I am sure a lot of other players prefer to play them instead. The new jungle does kick the ass of a lot of tank junglers but there are a couple of easy ways to mitigate the harshness of the first and second clear.
There are two methods of bolstering your early clearing and they are both very viable but require different factors to be taken into account. One of the methods is far better if you do not know how strong your leash will be, or if you do know how strong leash will be and it happens to suck, and it unfortunately requires you to tamper with your build and alter it into something that may not be preferential to your preferred jungle tank. The other method allows you to take any build you want, runes and masteries, but, even with a leash, will often require you to forfeit your potential for an early gank and hinder your versatility in clearing.
