The fact that the last handful of releases from the Fun Publications era of the TransFormers Collectors' Club and BotCon were branded as Combiner Wars toys, rather than coming under the Club's own brand, Timelines, was an early sign that changes were afoot.
Hasbro had pushed Combiner Wars hard - one might even say beyond its limits - and, while a custom gestalt made the ideal basis for an exclusive boxed set, they had produced so many retools of their own that, by 2016, there just weren't any surprises to be had with the format. Hasbro themselves had already moved on to Titans Return and, while FunPub's use of an older toyline was essentially par for the course, there just wasn't enough mileage left in Combiner Wars, even with a set related to (or perhaps retconning) Dawn of Futures Past - one of their very best BotCon sets.
Their take on Tripredacus was deeply uninspired, utilising some of the least highly-regarded molds, which were nevertheless among the most frequently retooled. The only real highlights of that year's show were a retooling of the RID2001 Megatron mold as TransMetals Megatron, and 2015's TransFormers Legends Slipstream mold (itself a retool of the very first Windblade toy) as Airazor.
So... why did I also acquire Terrorsaur? Let's see if I can figure that out, shall we?
