I don't understand how it's supposed to function. As far as I know pool costs are there to stop spamming.
This I guess means if somebody gets an
abnormally high amount of units, they'll be in minus areas with their pool and will have to pay pps every time they want to play with that setup.
At the moment though, you get into minus areas if you field 4 PIVs (-12/36) or for example 3 pumas and 4 bikes (-3/36).
Now yes, we do have a "reserve pool", but shouldn't that be there for the lvl9 companies which find themselves with left-over resources if they
don't get 5 PIVs and 4 pumas + some bikes - which is enough to force them to pay PPs every match, remember too the last advantages are gotten at lvl8, where you still really care about having a decent pp income per match - and therefore instead of limiting spam really just limits your choice of units if you don't want to pay pps all the time.
I just find it kind of ridiculous that for 4 PIVs I'm already taking a large slice off my reserve pool, while having a perfectly normal amount of units.
Adding to this there are several strange things I don't understand like Officers being counted as infantry.
Maybe the pool system needs a major redo?
(and yea, I'll admit I thought of posting this because of suddenly finding my lvl8 def company on 18 PPs oversupply at the end of a match...)
