Tactics for Rampart.

How will slowing and speeding up help against elementals? Will I slow them down and just wait? The AI will summon 7 stacks of them (this has happened many times). What will I do then?

And another point.

When playing with STANDARD maps, I would dismiss and re-hire the same hero as many times as my resources allowed. But on random maps, I would only split up a hero's skills a couple of times. There doesn't seem to be a need for it. Why? Because the map isn't fully revealed, and you don't know where to send the hero anyway. You send him, but it turns out you sent him in the wrong direction, and you've wasted 2500 gold for nothing.

The opponent summons elementals. In response, mass speed up. He's doing something. Wait. Then punish them all, taking into account stats and skills. Round 2. Continue the punishment, if necessary, add mass slow.

Regarding splitting up skills. Hide monsters in a corner near the spawn point. It takes 4 days to travel from the castle. Gurney, for example, reaches the 117th tile, and then what? Waste 4 days on the return trip? No, we do it differently. Gurney gives his troops to a secondary hero, and he splits up his skills and returns home (to a secondary castle?), where he spends the night with a fast unit (a greased goblin, a fairy from the third hero, etc.). The secondary hero stays at the spawn point. On the 121st tile, the secondary hero buys a second unit, and we pass it on to Gurney in a chain, and he continues the punishment. This way, for 2500 gold, we significantly increase the pace of the game.
