Hello, is the Feredir getting looked at for his ability to capture an inn then kill the troll and clear the structure with Kin Lai spears? This costs you 550 resources (150 fere+400 kin lai total but unlocks the map for you nicely + gives you early spears+ gives a huge amount of resources and no other faction in the game can match this type of clear. Nobody can clear a troll lair so fast but WR can for a measely 550 resources or less if they send in daggers to clear it instead of Kin Lai, which is feasible since Trolls respawn slow. I am aware Gondor and Rohan can attempt something similar with their Mer/Pip and stealth, but those two can't solo a troll as easily as a Feredir can.
I've tried countering this when it's used against me but it's not easy to know which Troll Lair they would clear (usually 2 inns on the 1v1 maps) and you have to fight over the treasure when you do get it right. Perhaps a Feredir cost increase or removing his ability to capture inns with his stealth like he is currently doing would be a nice nerf, so the player would be forced to kill the troll first with Feredir then capture.
