First off, the list seems totally playable, but not optimized.
The first thing i see as an experienced player is that you seem to be playing both the fennblades and the kriel stone without their attachments. You should try and get hold of a fennblade attachment and a stone scribe elder. Those two make the units function "properly". Fennblads without their attachment are a sad sight compared to when they have their leader and drummer! Also, the elder for the stone gives you a +1 STR to everything when you need it, and that translates in to a significantly higher damage output. It also can make you immune to continous effects (and that actually negates several feats in the game entirely) or it can remove incorporeal so that you can bust some ghosts if need be.
The second thing that i would change is the number of light beasts. You come from a journeyman league, and you are forced to take those there, but now, when you are a big boy you do not need to. Having one axer and one bouncer is fine, but i would leave the second bouncer and the impaler at home, and get another heavy in there. Another Bomber or mauler or Mulg or Rök (if you go borka) would be splendid! An EBDT is also a fine option, and a model you will want in the furture. I also see you have no fury management, so whelps or a chef is mandatory i think to get the pull power from the list.
The fennblades are a good idea with Borka at least. If you add in a chronicler, they can be DEF 16 against shooting, and that will sure up their biggest weakness. You need a few extra points though. With Ragnor, i do not think they are very good though. He does basically nothing for them. The Kithkar is pretty good for them, but i really prefer a Fell Caller. Being able to give them pathfinder is very good early on, and +2 to hit is obviously better than +1.
So, an example of a some what more refined list that still carries a lot of the same feel as you have in your current one would be this:
Trollbloods Army - 75 / 75 points
(Borka 1) Borka Kegslayer [+28]
- Pyg Keg Carrier
- Dire Troll Bomber [19]
- Dire Troll Mauler [15]
- Troll Bouncer [9]
- Troll Axer [10]
- Slag Troll [10]
Trollkin Fennblades (max) [15]
- Fennblade Officer and Drummer [5]
Krielstone Bearer & Stone Scribes (min) [6]
- Stone Scribe Elder [3]
Fell Caller Hero [5]
Stone Scribe Chronicler [4]
Swamp Gobber Chef [1]
Swamp Gobber Chef [1]
I couldnt quite get the points to work out to get a 3rd heavy, and had to settle with a Slag Troll. You can probably buy a used one really cheap, because many troll players have 4 of them and use 1 tops due to the changes in the edition. The Slag works like a heavy if you are up against Warjacks at least. The list is similar to what you already have, but the packages have been tweaked for extra performance. This is not quite what a tournament list would look like, but it is a well balanced list that you can play against almost anything, and it will help you keep learning the game.
