I would like to give my appreciation for the continued support of Ranger Traps. It seems like every other companion has new traps to use, or new archetypes to make use of them, and as someone who really likes the idea of using traps, this is awesome. It makes me look forward to each player companion to see what's available.
I think this would be a great opportunity for a Player Companion book as well: Trapper's Toolbox. It could contain all the ranger traps released so far, as well as references for what other books contain trap using archetypes.
The Ranged Tactics Toolbox had a good amount of advice on avoiding common issues related to ranged combat, and I think there is ample space to give the same sort of advice for trap using. For example, how do you deal with the need to prepare the battlefield before hand? Ideas on scouting, trap placement, ways to hide them further, how not to bog down every combat by spending 20 minutes alone time with the GM on scouting and trap placement, etc.
I'm also curious if we'll see any Ranger Skirmisher Tricks, as there are now three core classes/archetypes that make use of them, and they're in a similar vein to the traps!
