A commenter on one of my other sites (leave a link so I can credit you, I see your comments!) pointed me to Tobold’s most recent post, where he brings to light an exploit where goods from the Satchels of Helpful Goods can be used by level 19 characters, and how it’s having a bad impact on the 19 bracket in the EU. I’ve only played a few 19s in the past month in the US, and I didn’t notice anyone overwhelmingly powerful – all my losses were definitely due to getting outplayed – but this is one of those things which can cause big problems for a bracket until it’s fixed.
Blizzard has supposedly fixed the satchel so you can’t get these rewards anymore at low levels, but the gear still remains. Unbalancing? Yes. Likely to remain? Also yes, this doesn’t seem like something that’s easy to fix.
We’ll have to see how big an impact this has on the lower brackets.
