I agree with the idea of a temporary ability
not as toggle weapon. I misused the term "switch". I can exclude the chain, mine was an example to better understand that the improvisation is an intrinsic characteristic of the cave trolls , at least concerning the movie
. Julio I'm not so convinced to link the ability to Bolg. Because we cannot call it exactly an "upgrade" (as for example happen with the trolls of Mordor).
guys, As off-topic, but related to MM as well. Speaking about my personal taste, the design of Giants from vanilla is a bit weird, in my vision they need a rework. I just think the same about half troll, and if I'm not wrong the team removed them and also the spider riders because they don't fit for the new MM faction (totally agree with that).
Maybe I'm I too sticked with the traditional form of mountain Giants, the original one coming from Norse mythology (The Jötunn race). There is very little amount of material from the Tolkien's lore about this matter. Ah, just to make it clear from the start: no stone Giants from the movies, I agree they don't fit.
