it's very possible that the drop rate was reduced to fall in line with the recent change for mogu rune of fate acquisition. since the mogu rune cost was reduced from 90 to 50 lesser charms, I'd imagine the lesser charms dropping from battles was prolly halved (or close to) as well.
it seemed like they had nerfed it..then the past couple days I managed to get 120 without even noticing by pet battling. Just make sure all your pets are within 5 levels of the one you are fighting. Not at home or i'd test but I was getting alot of them fighting level 23-25s so not sure if using level 1s in SW/ORG still gives you alot like it did.
Just my observations.
Even though it was repetitive/boring/mindless - getting a lvl 6 pet and killing lvl 1 critters in Stormwind did the trick for me. Haven't been able to play in a few days, learning that they nerfed it is depressing, there's no way I'm going back to doing dailies. What a bummer.
Can anyone confirm that AFTER todays maintenance, they got a good yield of coins from pet battles?
No one needs to confirm anything, doing battles for 10minutes then complaining you don't get any coins isn't too reliable.
Back to the actual topic, the amount of charms you get is the same as always between 2-3 and 6, with it being completely random with absolutely no system behind it apart from a % drop chance. I've had intervals going from less than 5minutes to move than 30-40minute between coin drops.
With the nerf to the weekly I don't think anyone really cares about this anymore with people sitting on more than a month's worth easily even on alts.
There are multiple people here reporting that the pet battles are not giving them anywhere near as many coins, and you did not do any pet battles today from what I can tell. Which means that they may be right. Stop being thick. Let me know if you did them today, as in within the past 9 hours, and got lesser charms of good fortune at a rate that is consistent with your results prior to today's maintenance.
