Your point was that Blizz make banwaves around content patches.
But I have to disappoint you, because they "forgot" to banwave Honorbuddy for the most important content patche in the last 2 years - for the Legion Launch on 29th August 2016
Yes, they worked hard on it - as result HB had several TW events, but Blizzard detected and banwaved almost all other 3rd party tools except Honorbuddy ~2 weeks before Legion launch, including huge bait of player base of the the combat-routine bots like SBR/FH.
Do you truely believe, that Blizzard would banwave any non-HB bot, but leave Honorbuddy relaxed for almost 2 and half months after the expansion launch(till Nov 10th)?
