For me it depends on the opposition and the situation I am in. Before it was always 2 trolls and a gobo, but now I vary it up which can keep my opponent on their toes ( I hope ). If I'm against a team that is not really bash (i.e an elf, skaven) and I'm receiving, then generally it is 2 trolls and 1 gobs. I can vary that up with 2 trolls and 3 gobs if I want the gobs to block. If I have the weapons that can be another formation as well with both trolls, 2 gobs and fanatic on the front lines.Just to throw something fresh into this thread. What LOS do you gobbo coaches prefer to use and in which matchups? I find that, while the most common LOS of use is the two trolls and Goblins, I am beginning to find, inversely, 1 troll and two gobbos or three Gobbo LOS tends to work significantly better, that way I have two trolls ready to "intercept" or at least ready themselves for the opposition advance rather than be pushed.
I find the only times where a duo troll LOS is required is during the early team values, particularly vs Zons and agility teams like the Elves. What are your thoughts?
I find against bash teams, on the offence you can do as above, but it is on defence that pulling your trolls back of the line is really good idea. If you leave them on the LOS, then you will be ganged up upon and your defence can just crumble, leaving you with just gobs to take down a ball carrier/cage. I normally now place 3 gobs on the extremes on the line, with the tolls 4, or more tiles back. This leaves you free to move your trolls to where they are needed, actually creating road blocks to slow the opponent down and stop them just brushing you aside and scoring at will. They generally have to work for a score!
Also one time I had my SS goblin on a corner on the LOS and was able to get pushed around so it gave me a chance at annoying/going for his ball carrier Having just gobs on the LOS can really annoy the other player cause sometimes they don't drop and they end up wasting several pieces turn just to try take down a gob
Against agile, quick teams I tend to struggle on the defence as normally your tolls are too slow, so the ground work has be done by gobs. So I find trolls on the line are best just to try and tie up as many players as possible.
The other time I vary that, is if I'm going for 1TD score with TTM then a troll is obviously pulled back. Break Tackle can also kinda hide this tactic as well, but if you 1- nil down, then I expect my opponent to expect that play
