I just did +7 Waycrest. I want to do a +10 and Ive never gone up that high.Highest Ive ever done is +9.
I want to bump up my weekly chest to 465 gear and I gotta do a +10 in order to get that.
My ilvl is only 457. I was wondering if that’s good enough to do a mythic that high up.
Yes, it is.
Generally you want to stay within 5 or 10 iLvL (5 if you are a healer or a tank) of whatever drops out of the content you are looking to run.
A 10 drops 455 iLvL loot out of the end of dungeon loot chest, so the absolute lowest you want to run it on is a 445, but 450 would be fine.
But also iLvL is not as relevant as other metrics, such as Essences and Corruption effects. So bear that in mind. A 445 iLvL character with 4 rank 3 BiS essences will beat a 460 iLvL character with only 3 rank 1 or 2 essences generally.
Yup 
Yes

Yup you’re fine with 457 ilevel.
Theoretically, yes. Ive done up to 15s in almost WQ gear; however, with the way group finder works, you will need cutting edge with 480 ilvl and 3500 io to do +10s.
Easily, do your group a favor though and learn what the +10 affix mobs do. What to interrupt/stun. If you were Horde I would take ya and show u the ropes 
Just look for a run that’s listed as completion.
If you have a good team you can all be 20-30 ILVL lower and do a 10, but it has to be the right week and dungeon or be damn good, like you cannot do tyrannical AD with too low ILVL or KR on fort week.
A high enough ILVL can brute force a dungeon, but too low and you need to pick and choose or you won’t pass, let alone time.
For a 10, I’d also make sure you’re gemmed and enchanted, even if with the cheap stuff. Being generally familiar with the mechanics that change on that 10 will help as well, because it adds 4 new mini bosses.
Depends on your whole group whether you’re successful, but I’ve seen +10s done in less.
If you can push your own +8 or 9 key, it won’t really matter what your IL is. If you pulled your wait in that previous key, you will be fine.
Put some enchants on and gem your gear then go for it. Makes you look bad to potential groups if you aren’t willing to drop 2k on some gems and enchants to contribute to the run fully.
be within 15 ilvls of the content you are doing and you will be fine.
that is the golden rule. if you are heroic 460, you have the power to down mythic and collect 475s.
It doesnt matter as long as your IO score is up to par then youre good to go. IO score means more than ilvl these days.
what’s IO score? is that achievment lvl?
Ilvl is just fine for +10, how well your group plays will determine if you have a good run.
Raider.io score is a website that tracks the Mythics you run, pulled from wow armory, and assigns a value based on how well you timed that key.
Basically the higher someones IO score, the higher keys they have done, and one hopes a reflection of their experiences. Though it can be cheesed with carries.
Or hear me out here and this is so amazing. Push your own key. You know coz you can also do that
