Zed will soon be available for testing on the PBE. Thanks in advance to everyone for all of the testing and feedback that will occur over the coming days to help us release the best possible champion.
The version of Zed you'll be playing on day 1 is definitely not complete. He is missing a couple icons, and has a few known particle and animation issues. I encourage everyone to report things like this.
I would also love it if you all would dig even deeper. Test and give feedback on those edge cases and unusual circumstances we that might not have come up during our internal testing. In particular, Zed has the most ambitious set of non-primary animations/particles of any champion we've ever made (emotes, recall, etc.). I'm confident there are a lot of bugs still to be discovered with these.
In terms of reporting -- detail is everything. Please try to give as much context as possible to your reports, including but obviously not limited to, game time, map position, other champions present, and any other variable that you feel might be relevant. The best bug reports describe the set of conditions necessary to replicate the bug in question.
A final word on Zed himself -- Zed is a fairly technical assassin. He rewards flexibility in comboing his abilities; his pattern is not as straightforward as a lot of our other champions. As PBEers, you can help us not just fix bugs, but also to make the play experience more rewarding for everyone after launch. With that in mind, feel free to use these forums to discuss what worked for you and ways that we can better communicate the possibility of particular skill/skill combo uses to other Zed players, through particles, tooltips, skill tweaks, etc.
We know that Zed is great midlane and jungle, and can succeed elsewhere with the right matchup/team comp. Keep that in mind during champ select.
