I've owned a pob, supplied a pob, sieged pobs and defended pobs. Honestly this is a welcoming change because a pob can still last a fairly long time and it's not that big of an issue if you find it in a well placed spot. Doing this wear and tear change is a nice change as it encourages people to actually keep pobs up rather than it just lasting forever in ungodly locations for weeks on end.
(Frankly i just get irritated the bases don't get used very much. you're not meant to really run a pob by yourself)
