It seems clear to me that ZOS needs additional people testing releases, either internally (preferred but probably not realistic) or externally (which is what I believe this PTS forum is meant to serve as). The issue with this forum is most people only care about things that directly impact them, i.e Combat changes... many of which are not bugs per say, but subjective feelings on changes.
I'm proposing an incentive for players to root out and report issues; bugs that are reported and found to be valid by ZOS staff would be rewarded with a small crown amount (perhaps 20c - 100c depending on the severity of the bug). This would encourage more players to spend less time in the PTS server hitting practice dummies, and more time exploring and trying to 'break' things by
way of giving them some good feedback, instead of what currently feels like 'yelling into the void and wondering if anyone is even listening.'
