This pretty well sums it up for me as well, it comes down to points and the army feeling too small. Were I not running a Carnosaur (which is still a stretch for me, thinking about its cost), I might consider a second steg with the chief/lance. "From other hand the skink-kroxigors unit is reall cool but u dont have tactical avadage..." Two of the mixed units could beat a stegadon fairly easily. Setup the typical wedge formation, the two blocks near each other facing inward. Steg charges one block, which flees, causing a failed charge. Other block flanks, krox goes after rider while poison goes to the steg. Two ranks and outnumber and whatever wounds caused now need to be overcome by the steg and crew. Meanwhile the other mixed unit is free to rally and reform. If the steg decides not to charge, he can be charged by the mixed blocks who have the same charge distance... and the steg can't flee as he is immune to psychology. Alternatively you could just keep pelting the steg with 11 poisoned javelins from each unit over and over again, fleeing if it ever gets to charge. A 124 point block that has movement 6, 3 ranks, 6 poison attacks, and 3 str 6 attacks, the ability to toss 5 poisoned javelins, and doesn't need to test for fear is lacking some things, but tactical advantage is not one of them. It is a less direct combat style that involves more baiting and fleeing, but the blocks are still solid enough to threaten flanks.
