Gremlins' shots are not infinite (unless there is an ammo cart)
Regarding the unfairness, IMHO the question sounds incorrect. Let's remove the secondary spell casting after attack from the mighty gorgons, basilisks, and wyverns (the gorgon's is totally rulez), lightning from the rocs, regeneration from the phoenixes, etc.
Where Crusaders lose to everyone is 1 hit, then a counter-attack, then a 2nd hit. If it were 2 times in a row, then it would be cool. Some don't survive until the 2nd hit.

Maybe Crusaders have more HP, but by the time they reach the gremlins, those will have tickled them a few times! ::) , but as for who wins I'm not sure...
Because for comparison, if we take 10 upgraded gremlins, then we must take 10 upgraded spearmen. Gremlins will tickle, but eventually the spearmen will reach them sometime :D Need to check.[/QUOTE]
You probably confused Crusaders with spearmen...
