We've dropped a balance patch just now. Two major changes...
Firstly: All skills that give Harvest Fertility have been buffed. Each point previously gave 5%; they now give 6%. The Tier 3 and Tier 6 skills that provide higher Fertility buffs have been proportionally increased as well, from 15% to 18% and from 25% to 30%.
In other words, Fertility is simply better now. We felt this was a necessary change.
Secondly, the effect of body parts on Harvest Affinity has been slightly adjusted. Bodies now give a 65% bonus to harvesting on a matching Node, up from 60%. Hands now give a 35% bonus, down from 40%, but also now only have a -10% penalty when non-matching, down from -15%.
This makes bodies slightly more important when harvesting, and hands slightly less important. Again, we felt this was necessary to balance out the additional weaknesses of having a typed body.
