Hello all, I recently took place in a 1999 point tournament using Tomb Kings and I thought I would pass on my thoughts.
Firstly, playing below 2,000 points screws us severely. I'm not sure if any other army gets screwed as much as we do, but I doubt it (Vampires?). No king means chariots are special, not core. Warriors cannot take a standard (so no 'undying legion' on tarpit unit of warriors). Maximum 3 special choices, particularly where as already mentioned chariots are a special, means a very difficult choice between units. In the end I went with a unit of chariots, a scorpion and a unit of 5 carrion.
Big units of chariots are silly. Because of the limitation on what I could take, I went with a large chariot unit - 5 plus my prince (so 6). This meant the unit was very unwieldy and easily outflanked. Lesson learnt; I should have gone with a maximum 3-4 unit, possibly without the prince.
Tomb swarms rock. I've always been of the opinion that swarms are terrible, but this is only really true when they are compared to scorpions. All those attacks, poisoned, means you are likely to kill something. Again in hindsight, I would have gone for a maximised unit of these guys and left the scorpion at home (meaning I could have instead taken a unit of tomb guard).
Bowmen can be good, or they can be terrible. And unfortunately, against most armies now, ST3 attacks don't cut it. They did manage to knock a unit of bretonnian knights down to 25% and a unit of 10 bowmen withstood an ogre charge (allowing me to countercharge with several other units, winning me the game). I'm really hoping the new shooting rules in 8th edition change this, as they really need to be taken in large units to be of any use.
So overall I did terribly, but had good fun. I do think we need another core unit that was vaguely useful (*cough actually decent heavy cavalry cough*) as I found an army comprising mainly warriors and bowmen was, frankly, quite boring. I wish now I'd taken a unit of ushabti - a big change for me, since I had previously dismissed them as being too expensive. Carrion are deceptively terrible. being toughness 4 and having 2 wounds made me put them in situations they really shouldn't have been in - too easy to hit and I forgot how many times combat resolution made whoever was left go pop. Only really good for hunting down warmachine crew.
Oh, and also, a hill in the middle of the battlefield - which means an enemy mage can freely draw line of sight against your hierophant with magic missile attacks, wherever he is trying to hide - sucks!
