Well i'm on the path to get them i've been on that path for a year now. I just really don't feel like spending a year trying to work for something and then not being able to reach it, that's a year i could have spend doing other things. I started on solely without even knowing if the skins are usable after Legion, which was already a shit place to be, I haven't enjoyed the skins in Legion, I've been basing getting them so I can actually make use of them after when I don't have to wear hidden skin to farm 1000 honor kills instead of the cool one I want to wear, just in case that in the future i might like the hidden skin more than I like that one i would like to wear in Legion.
The difficulty of the challenges is subsided in the end by the gear, possibly or possibly not on all specs, then I'm to do what i did with the warlock greenfire quest in MoP. I'm going to spend 3 months and 600+ or something pulls of ramming my head to a stonewall until it's done. In the end I fucking hated that questline and I hated my warlock, I still do, if I have to enslave one more demon ever again i'm going to find the dev who put that spell in to the game and force feed it to them, but hey I got a title.
The bigger problem is that there's not enough time. Getting there takes enormous amounts of time and I pretty much do this 12 hours a day, every day on multiple characters. Still i'm afraid the it's not going to be enough, that it's not even possible to do this in the given time frame. Specifically if I have to start bruteing some challenge tactics with my head to the stonewall for months on end like that warlock, months that I possibly don't have. That we really don't even know cause no one wants to tell us. It's estimated that 7.3 will hit in the next months and last raid tier opens in november.
Lessons Blizzard learned from WoD was not to dryspell content between expacs, meaning we might very well be looking at the next expac in january or february depending on gamescom announcements. Essentially leaving about 6-7 months to complete it all, when getting to this point has taken already what 11 months and it's not even close there yet. And highly likely getting fully geared towards the very end, meaning it'll be up to the very last weeks of working the challenges. Something I did with the MoP CM sets, I was in there pushing 24 hour days in the last week just to get my shaman set and again I hated doing that, but in the end I got the set. I hated playing the shaman after so really it's bittersweet to have the set cause playing with the class now is just bad memories and source of immense stress. There's no prestige or reward in challenge, only stress. It's nothing but a ball of ugly growing stress that's just going to burn you out in the end.
Heck the only toon I play to reach pvp prestige cap like mad man, more hours than my main just because eu alliance pvp is so shit, is currently at prestige 5 and needs to be level 15 to unlock their skin and I've played that char now for 6 months out of the 11 to get that far, it's looking like it's going to be mathematically impossible, not much more you can do when you're already grinding stuff 12 hours a day every day. One thing is already sure if I ever get to that prestige 15, i'm never ever ever going to heal anyone in pvp again. If there's something that makes you hate other people and humanity it's that, be a healer in pvp and get ready for apocalypse after.
