this is an interesting question and as you say they certainly werent the cliche 'warhammer' woodelves, but we do see them using stealth in favour of fighting, for instance in the hobbit with the dwarves in mirkwood.
they did however take part in the battle of 5 armies, storm dol guldur and repel several attacks in the war of the ring…..so i dont think they were 'weak' per se but i do have a feeling this is how they shall be portrayed
i just hope they dont go down the film route of making woodelves into some ninja warrior race like legolas
That's what I thought. Always remembered the Elves were particularly impressive throughout Tolkein's works, much unlike Warhammer Elves. And ninja warriors would be dreadful. To be honest, FFG did a pretty good job with the dwarves not to make them horribly cliched, and some of them really nicely reflected the lore of the dwarves. I expect them to do a good job with the Silvan keyword, in time. The Mirkwood Runner is still, in my opinion, one of the best designed allies in the game. Elegantly designed, I've always felt.
