I don't have an issue with Beta Terminals having a better recycling efficiency than Alpha.
I don't have an issue with reducing the bonus of a skill to avoid a potentially exploitable situation.
However, I do have an issue with Ninja Nerfing, more so when Dev's don't fully explain the reasoning behind such actions. Ninja Nerfing, generates distrust of Devs, or particular Devs responsible for that area of the game. Failure to communicate the reasons behind a nerf and the need to ninja nerf comes across as "we are Dev's we will do what we want to do.... deal with it"
I also have an issue with not resetting and reimbursing the EP and the standoffish attitude the Dev team have taken on this issue. The Skill has been reduced by 1/3 of its effective value. As a result the Ratio between effective Value and EP cost has changed to the point where I believe the skill is too expensive for the bonus it gives.
In response to this I believe one of the following actions are required:
Either the skill should be reset and EP reimbursed so people can re-assess the skill and assign EP accordingly - However I can see that this course of action brings about it's own issues cause it sets a precident and raises the question "what is a significant nerf?"
The alternative and compromise is that the skills complexity gets reduced (say complexity 2) to reflect its reduction in effectiveness and the difference in EP gets reimbursed. I feel this is a more acceptable and transferable precedent which acknowledges the change in the ratio between benefit and cost. The precedent also affects buffs to skills in the future and players can expect that the complexity for buffed skills will get increased and will have their level reduced to match how much EP they had previously spent on the skill.
