I love using saurus units. I came from using dwarves and I always wanted two things that dwarves could never get, spears and more than one attack. I always outfit my saurus warriors with both spears and the blessing of sotek, if you are fighting things with heavy calvary, such as brettonia, spawning army (not sure the acctual name here) of Sotek is a lot of fun, (Provided you get beast cowers with priests).
After you have saurus with sotek you can put a BS bearer in the front rank, with the scimitar, also blessed with sotek, and that gives you 29 attacks on the charge and 19 attacks if you keep them in ranks of 5. Which deffinatly trumps the dwarf 5 attacks in ranks of 5.
That being said they are expensive, but they are deffinatly worth their points, although it would be nice to be able to equip them with gw sometime.
On a side note could someone explain what ASF and Tla stand for? Thanks.
