In the spirit of transparency and open communication we would like to explain the process that led to the stamina issue.
Firstly, Primalist robes were the least used armours in the game, so we were trying to find a way to increase their desirability. While exploring possible solutions, we came across the stamina regeneration being disabled while sprinting issue, and thought that enabling this would also have a bonus effect of increasing Primalist armor usage. So we experimented with enabling this option, and we had mixed results.
On one end characters that were wearing Primalist armours and used food, had a net gain on stamina even while sprinting. While this may be desirable for these armours, we were unsure if that change would make them an overwhelmingly popular choice. On the other end, characters without food and without wearing Primalist armours would see their stamina bar, especially when it was full, drop much faster than before.
We experimented with some values in combat situations in the allotted testing time, and came to the, in retrospect, premature conclusion that these values were an acceptable initial implementation. As we mentioned in the patch notes, these values were subject to change depending on your feedback, so today we will be applying a patch to address the issue.
In light of your feedback and of the complexity of the problem as well as the upcoming siege engines patch, we decided to alleviate the issue by setting stamina consumption for sprinting to 40% cheaper than its pre-patch value, as well as revert the change done to stamina regeneration while sprinting.
Please regard this change as a temporary necessity, while we thoroughly explore possible options and values for this issue.
We would also like to address the issue of the changes that were presented to the MVP forum but did not make it in this patch. As stated in the relevant thread, perhaps not too clearly, all the proposed changes were presented as discussion topics and to gather player feedback. We included what we could in this patch with the rest of the changes being in the evaluation/implementation phase at the moment.
In closing, we regret causing distress to the community, but do believe us when we say that all changes done were due to our eagerness to please you, even though in this case it seems that the effect was the exact opposite.
