What is "hit and run"? Please explain.

Elves have good chances of avoiding being run down (well, look, they've popped up here too, because they're overpowered, IMHO). Take Golems as your sworn enemies and keep your eyes peeled! Basically, you set up Unicorns (2nd tier) and someone else (you can use only Unicorns, or divide them, etc.). Cast Antimagic on someone, and it also applies to the Unicorns. Then a couple of volleys of arrows, and you're done ;) Elves are good at any stage of the game; they have a less significant counter in hit and run, and they can also use it themselves! Elves are IMHO the strongest in Heroes 5... and someone still believes in balance? And don't forget the Necromancers - they're beasts at diplomacy too :)
