Probably more like lack of manpower & resources.
Here's a fan made counter, thanks to bagstone#2613......
It will be dead if they don't do anything about the rampant botting.
Got guys on my friends list who've been playing nonstop since s12 started. Last time I checked, one was soloing gr103 for four straight days while on DND mode.
Even though I've been playing s12 as much as humanly and socially possible, these guys are still 2.5k paragons higher.
This is very discouraging and many legit players might either consider botting for s13 or move on to other games.
2 or 3 ban waves a year is simply too little too late to save this sinking ship unless they figure a way for instant banning on the spot when a bot is used.
"blizz intended to make jade and maybe arachyr more competitive with gargs"
I don't get it Blizz.. Competitive ?
You just made the boring Jade OP and the fun HT/garg irrelevant.
Not long ago you nerfed the Jade for being OP, which gave rise to the HT/garg build.
Get your sht together.
