i've seen the terradon behind a unit thing before and it is quite effective. placement is one thing by what i mean tactic, but to put it metaphorically, instead of having a bunch of independent gears (units) spinning separately, how can they lock together to work more efficiently with all other units of the army.
an example would be (and this may or may not be rules accurate) a co-operation of 4+ different units.
a group of chameleon skink shoots at a relatively small unit in the back weakening it then continues on to a war machine if there is one. next a group of terradons, if place correctly on top of a hill see the small weakened unit and charges it while passing over and dropping rocks a large block unit. then a large block unit of your own can now charge the weakened block unit. skink skirmishes can come into play in many of these areas; the follow the chameleons and assist in shooting, participate in combat (if units are very weak), or act as a barrier to slow the interference of other enemy units. all the while one can also have magic assistance. best of all this can happen in about two turns if you deploy right.
the point i'm trying to get across is how can a player use large portions of their army to create a smooth, powerful current of destruction
