Pestilence should be faster to clean

Petilence just feels too much for me, I need to explore I think its almost the full area to get to the boss.
Doing on starting areas can be easier, but having to reexplore the whole lowland meadows or the nameless pass is too tedious.
In my opinion, it should be faster to clean an area, so maybe to rebalance an idea can be make it reapear faster.
