from 2014
the Viper Pit and Eagle's Edge 3-packs.
Night Marksmen 2-pack, maybe the Socal Clash two pack if you really want Lady-Jaye.
The Night-Landing vehicle pack isn't bad either as well as the Battle Below Zero vehicle pack
From 2015
Vanishing Act and Sneak Attack 3packs are pretty good.
All the 2packs bar Swamp Steam (Blowtorch again vs Croc Master) are also worth getting, but even then it's not bad.
Both Vehicle sets are worth it and one is just 2 extra figures for the SDCC release while the other has a vehicle team swap for SDCC vs the retail one. All pretty good.
From 2016
Both 3 packs are good, with the Cobra one being better even though the female officer mold is a bit naff.
And you can't go wrong with any of the 2packs
No vehicles at retail that year, only a nice final GI JOE vs Transformers set with a good scarlett and repaint of Retaliation Zartan with A red Rattler and Soundwave version of the DTC 2005 Cobra HiSS (the transport one)
