29 twinks used high level mains on wow forums to complain and site armories of 20s as a unfair advantage to levelers. ironically were using various exploits for several expacs to get into leveling BGs. they even linked their wow forum complaint thread on this forum. changes to 20s did not miraculously happen on DF prepatch. after legion (template merged BGs) there was a war between 20s xpon and 29s xpoff, 29s lost at start of BFA, 29s lost in SL, (both f2P/vet stayed xpon BGs) 29s finally won on DF and 20s were now considered XPoff.
warband bank being cut off could have been exploits? could also be from subbed players seeing players 20 and below much stronger due to the SL gems, 3 gem neck, 2 gems rings etc. being obtained with much more ease? biggest exploit of warband from what i saw documented was the reputation exploit which involved high level players that were top raiders edging for every percent on gear, crafted stuff etc
https://us.forums.blizzard.com/en/wow/t/found-exploit-in-warband-banks/1908759 here is obviously a paid player, reporting that his non active account with a 20 can move stuff into his paid account as a exploit. i wonder if he moved them back so he could not use the items? this smells like a paid twink on a agenda against F2P and vets, not sure if there were other hidden agenda threads or reports like this? like the 20 vs 29 war it worked
owned core site, some of the posters here like to post there, the site is known for use of mechanics, exploits, hacks, etc. alot of stuff from owned core gets reported to blizzard. people even pay a sub to get access to the elite stuff, so they can report that
youtube, twitch etc also brings negative attention, last expac there was some comments by high profile wow influencers concerning the WOD gear, low levels, and ooze.
