Patch 09/12/2014 (12 Sep 2014): We have reverted the changes made to Gamma Rays Tier 4, which caused issues with the Tier 8 bonus and Recycler.
Patch 09/11/2014 (11 Sep 2014): Gamma Rays T4+ will now use Rapid Tap mechanics. This resolves a timing bug with T4 casting. Buff icons no longer display denoting the current cast time as the Rapid Tap UI addresses this need itself. There is now an 8-second limit to cast all 3 beams before cast time is reset.

Strain (1 July 2014): Fixed an issue where using Tier 4+ would consume all 4 Actuators following Energize.
