Got another game, this time against Ossiarch Petrifex elite. Didn't change anything in the list either. As a result - wipeout by turn 3. Yes, 4 full salamander packs are literally capable of wiping out petrifex elite list in 3 turns. It had only 60 mortek guard and no harvesters, but still.
Once again, starpriest and skinks didn't do much. The problems is that I cannot bring 20x skinks in reserves because they are needed to score objective. Starpriest, however, brought me 3 CP, which is nice. But still I think about what can be done to improve their potential.
I feel like 4x packs are redundant. They are just hard to fit to strike turn 1 because of terrain. Maybe, one pack should stay on the ground to defend home terriotry. Or it can be divided in 3 single salamanders, which will increase deployment choices, but we are not chosing who goes first anyway.
Another idea is to drop 10 skinks and a starpriest for 6x terradons. They can help to clean chaff before initial alphastrike and hunt small units sitting on objectives.
It is also possible to exchange single salamander pack for razordons to shoot from the back row. 18" can be very handy in this case. Or just drop one pack and add 20 more skinks and a priest to get 40x classic skinks pack.
They main weakness so far I can think of is cheap MSU, which protects main body of opponent's force and, ideally, it is a ranged force. Any elite army will be in a great disadvantage.
EDIT: I am about 3 years into tabletop gaming but today I felt that my list may be a bit over the top for the first time.
