I'm dedicated, I never miss a raid day unless there would be something urgent, willing to learn and adapt to new ways of thinking/strategies. I take criticism pretty well I don't get upset over it but try to improve and be better. As for my character, I like to spend time on it researching logs or comparing myself to other hunters so I can be prepared and perform accordingly. That also goes for new bosses, raid tiers, expansions etc. I come to raids prepared with everything that I need (125food, runes, flask, pots) . I like to craft pieces that I think won't drop for me until the later mythic bosses, I had 3 crafted pieces until I replaced them with some lucky drops that I got.
As for my character I know the most things I need to such as the opener, rotation, use of deterrance on certain mechanics, if I'm unsure about let's say what trinket is the best for a specific boss I ask other hunters maybe on other servers about it, test it on simcraft etc and draw a conclusion from that. Same goes for my talent choices even tho they aren't that complicated as the trinket situation. I know my boundaries of what my class can and cannot do.
With macros I mainly have cancelcast macros for my deterrence, disengage and tonic and of course a deterrence cancel macro,  if there is a specific interrupt I need to do on an add I do a focus macro for it.
I also use WA's for important debuffs like for example doomwell on gorefiend, and to track my own trinket proccs, ring procc and the stand still buff. The focus bar I use the jshb addon since I think it suits me. For the other addons I use DBM, Exorsus + skada for the dmg meter, but that's kinda default and expected.
