My profile for the February challenge...
I need name suggestions, or I am calling him:
Gornash
A troll who rose within the ranks more so out of courage and strength rather than any form of intellect, Gornash is a rather special troll. He is dim enough to ignore danger and pain, but smart enough to throw a stone with accuracy greater than the average troll throw. Moreover, he may often appear to be winning do to his courage, while he really has simply lost count of how many enemies he has killed... at 2.

Gornash, the Troll Chieftain..........................135 POINTS
TROLL, MORIA, MONSTER, INFANTRY, HERO - HERO OF VALOUR
F7/4+ S7 D7 A3 W4 C5 M3 W2 F0
Wargear- Spear and Troll Chain

Special Rules
Immune to bow-fire
Ignoring pain and death alike, Gornash lives to drive his spear home.
When Gornash takes a bow wound, roll a D6. On a 4+ the wound is ignored, exactly if a point of fate had been spent.

Terror
Throw Stones, Strength 8, range 8"
Burly

Hobbit onslaught
Tiny folk are often overlooked, and thus they have a strength against the larger, but dimwitted, creatures of Middle Earth.
If a hobbit model wins a fight with X, and is at a higher elevation so as to be at head level, they may instead roll a single d6. On a 4+, they may climb on him. The immune to bow-fire is no longer in affect while the hobbit remains, and the hobbit will not be hit by friendly bow fire. The hobbit may get off of free will, or attempt to remain on top by rolling another D6, needing a 5+. Only two hobbits may ride X. X is also reduced to attack value 2 and fight 5, as he is trying to get the hobbits off.

Body Slam brutal power attack
Gornash never knocks on the door, he just walks in, regardless of whether or not is barricaded.
If a terrain piece is in the way, Gornash may charge it in a straight line. If he destroys it, he may move his remaining movement and will continue to damage any terrain obstructions in this way, stopping once he fails to destroy terrain or engages an enemy model. He may not stop until one of these two conditions is met. Gornash receives +1 on all terrain to wound rolls, but may not use might. Should he fail to destroy a terrain piece, he takes one hit at the strength value of the terrain's defense value and may not move further for the rest of the turn. Additionally, Gornash suffers a -1 penalty to his fight value for the duration of the fight phase.

Should it model the troll in Balin's Tomb ?
The rules are quite thematic but when do you need to detroy terrains ?
Concerning the profil, it looks stronger than a chief troll from mordor but hey nothing too significant !
I would play it.

Yeah, he is the Balin's tomb troll. As for terrain: when do you not need to destroy enemy terrain? His defence and such is lower, but his rules make him rather nice. Glad you like him overall though!

Interesting, but you've listed him far too low at 135 points.

For comparison, a Mordor Troll Chieftain is 140 pts, and from that profile, here are the difference to your profile:

-1 Defense
+1 Wounds
+1 Courage
+1 Might
+1 Will
- added Burly
- and you gave him two special rules that benefit him

If you subscribe to the theory that each of those changes are worth 5 points apiece, that would make your profile worth 170 points. That 35 point savings is just too big a gap and would make this profile an 'auto-include' in every game for whoever had the option to take him.

But as I said, it is interesting.....nice creativity
