The interview for the troll design was interesting and the new scenario is a boon to the community as well. One thing that has been bothering me since first seeing the troll is why is he a blue banner? Borg's interview states that he did not want his power to be based soley on the banner color and I've thought that the troll would have been the perfect first red banner. The red banner fits with Borg's description of being a slow brute. The 6 battle dice can still be used instead of the typical 4 and may have caused a little less confusion (I read one player's battle report where they confused the blue banner usually using 3 dice as some how influencing the 6 dice troll decision and causing some rules issues when fighting on hills). I'm sure this was playtested and some flaw was discovered but I think it would have brought another level of uniqueness to this creature. I can only reason that forcing the troll to never move more than 1 hex emphasized his greatest weakness (IMHO): ranged attacks.
This brings me to my second comment...how to defeat the troll. Mind you this is just theory as I have not played with the figure or proxies yet, but it seems to me the best way to deal with the troll is through ranged unit attacks or lore attack spells. It seems that the weakest approach is a calvary attack as the calvary full units have one less figure and are very susceptible to the vicious counterattack. With the immunity to bonus strikes, archers hit the troll as well as any other unit in a die to die comparison, furthering their advantage.
Now this theory is not new, in fact I've read similar comments posted in this forum but I hope this begins some discussion based on actual gameplay experience. Are calvary doomed when facing this creature? How many archer units does it usually take to bring the troll to its knees? One shotting the beast is likely rare but if you get the mother of all ranged combos (Darken the skies and Magic Missle) is the troll flat out doomed? On the flip side, what are some devastating combos using the troll and what steps can one take to eliminate the ranged threat against him?
One last note to Mr Borg if he is reading... any chance of seeing the huge troll proto? ;-)
