Increasing map size should fix this problem but this has become an issue. There is simply not enough tier 6 resources to go around and having more tier 5 would also be helpful.
There is vast patches where there is absolutely no resources also. Its just not that balanced anymore as most of the players are squashed into an area about 15% of the size of the entire map to get the tier 5 resources as the others are completely useless to us.
Also if a resource is below 100k and has not been touched for over 48hours it should automatically reset to avoid constantly stumbling across resources some of which are into single digits they are so low and having to waste lots of time clearing them just so another will respawn. Its time consuming and very irritating.
