I would suggest that new harvesting system would be speed based instead amount of resources. And what do I mean speed based?
The amount of time it takes to completely harvest a node based on a harvesting skill.
for example:
a new player began with a skill in mining of 20 ( current not base ) and it would take 4 mins to finish mining a T1 resource node.
Now as he gains levels and increases his skill it would take less and less time to finish off a T1 resource node.
Once he becomes optimal ( 200 skill ) the time needed to finish off the node would be reduced to 1 minute.
now a suggestion on amount per nodes when completely harvested:
amount per Normal node would be 125 - 150
amount per Rich node would be 250 - 300 -- ( 15% additional time needed to finish harvesting )
amount per Mother lode node would be 500 - 750 -- (30% additional time needed to finish harvesting )
not like this is going to happen, but im just working out my thoughts on how we can improve Istaria.
Feel free to criticize the idea.
