The categories are vague, it isn't explained anywhere, and seems designed to put you off actually reporting bugs.
For example, say I'm running around in Cyrodiil, I see a zerg coming over the hill and so I use the skill Elusive Mist to get away. While I'm misting away, I get hit by a load of ranged attacks and suddenly I can't move at all. The zerg catches up with me and I die a painful death. I know that Elusive Mist should make me immune to immobilisation effects, but I see from my buff tracker that I've been hit with an Entrapping Poison so maybe somehow this has immobilised me despite being in mistform.
But how do I report this?
Eventually I figure out that there is no specific bug report feature, it's just lumped under "Submit Feedback" which is hidden under Customer Support in the Help menu.
So now I have to pick the impact of this bug. I think maybe it could fit under 'impairs functionality,' since my skill doesn't appear to be working properly. Equally though, it could count as an 'exploit' if the person is using this poison just to get people in mistform (assuming it's the poison that snared me). I guess I could even say that it's 'delaying progress' in PvP for me since I'm finding it difficult to progress when I'm dying to bugs.
The next bit,the Category and Subcategory, should be easy enough I think, obviously it goes under 'Alliance War/Cyrodiil' with a subcategory of... Oh wait, none of these subcategories seem right. The closest seems to be Graveyards/Death, since I died to it, but I don't think this is quite right. Maybe it goes under 'Items & Equipment' 'Consumables' but I'm not sure if it is the poison that is bugged. It could also be under 'Combat & Monsters' 'Ability' but looking at the Subcategory names in this category, it seems to be PvE focused so again this might not be right. Then I think, maybe it's a 'Character' issue, there's a Subcategory called 'Skill lines/Skills/Progression' could this be what I'm looking for? I choose at random, I have no idea what I should be picking here.
Now I'm on the home stretch, I just have to answer a few simple questions.
What were you doing? I was mistforming away from a zerg.
What did you expect to happen? I expected to continue mistforming away from the zerg.
What actually happened? My character suddenly stopped still after being hit with a lot of attacks, also there was an Entrapping poison, not sure if this is relevant.
Now I just need to attach a screenshot. Oh wait, I was busy running away from 20 enemy players and forgot to take one. I'll just submit it anyway I guess... I get a little message thanking me for my feedback.
I'm don't know about anyone else, but I'd love to see either:
1. An overhaul of the bug report system so that it is more intuitive and generally easier to use.
2. Some in game guidance(maybe a few examples) on how to actually fill in bug reports so that they're actually useful.
