So, champs is the last rep i don’t have for pathfinder part 1. Currently 26% into honored, and thats only because of the emissary today.
Is there NO way other than world quests, and the contract to get champs rep? This seems really unnecessarily slow. Getting 75-150 rep a world quest, when you need tens of thousands.
it goes really fast honestly, you can always try to track your mission board to see if you have access to missions that gives free coa rep, also if you have a ton of dubloons, you can buy a blue item that you give to the dwarf dude to get some extra rep, i know its not much but its a step in the right direction 
It doesn’t feel that way. The only missions on my table right now are, for some unknowable reason, outpost upgrade missions. And I’ve never done island expeditions so no doubloons. So really im stuck getting 150rep a world quest, when there are only, at maximum, six of them for COA a day, one per zone.
its easy to get dubloons, depending of the ilvl of your main, you can run mythic islands who takes 5 mins and the only thing you can do for now is being patient and do every coa wq when they are up
I don’t really have a ‘main’. I just came back to the game after not playing at all for BFA because it was…terrible. The highest iLvl character I have is my boosted shaman, sitting at 400. How high do I need to be?
its easy to gear up with m 0 and specially this week who gives extra pieces with m0
if you don’t want to do that, well you will have to keep doing wqs and wait for more emissaries
How high does my iLvl need to be for mythics? Both dungeons and island expeditions.
dungeons can be done as soon as you hit lvl 120, it depends if you have friends/guildies who can carry you till you gear up a bit if not then you will have to run heroics to get 415 gear, once you get to 410-415 ilvl you can be doing m0 without being a dead weight
same goes for m islands
You normally get 125 rep for a champs WQ, with the 100% bonus rep that becomes 250 per WQ.
6 x 250 = 1500 a day.
You’ll get it in about a week. (around 6 days as you are already about 1/4 into honored).
Plus if you get a champs contract, you get 20 rep per BFA WQ you do (regardless of who it is for) for now.
Do the Naz intro quests if you haven’t already. Magni will pop up and give you the quest that boosts your neck to rank 50 and gives a good chunk of CoA rep.
My neck is currently 74. But I haven’t don’t those quests yet, so if they do give a chunk of rep, I’ll get right on it.
People used to complain about having to get to exalted. Now people complain about having to get to revered. What’s next, honored? 
That also reminds me, the quests for the basic essence that you get from Kalecgos also give CoA rep. Pretty sure all quests originating from the heart chamber give more rep, though I’m not 100% on that.
I actually just tried to go to the heart chamber, because I was told that upon every rep milestone you can get a quest to get 10-15 free heart levels. I can’t actually use the teleporter, and no one outside offers any quests. I’ll get to work unlocking Nazjatar.
