When it comes down to it, the persian Immortal is really hard to beat. With an attack of 4, and a shield cost of 30, it is easily the most feared UU of the ancient era. In no other age is Defense/attack strength so critical than in the ancient age, and that 4 attack is literally huge. I really think this thing should cost a bit more than just the same ol' 30 that every other swordsman costs. I mean, when you compare it to a gallic swordsman who costs 40 for an extra speed point, you would think that the 4 attack is at least as important as that extra speed pt., if not more. Sure, units like sipahi and berserker are good, but they cost an arm and a leg, and cities of that era have much more defense modifications to rely on than those of the ancient era. So what do you guys think? Does anything compare when it comes down to overall effectiveness/bang for the buck?
