While in most cases I agree that range is greater than melee, here we have this dilema: I have 3 fresh beggars, you have 3 fresh ships o line. Using your 3 ships, you can attack my coastal units, bombard my cities, and kill my sea beggars if you concentrate your fire and get first strike. Problem is, with my three Beggars I can attack and plunder coastal cities more efficiently, and if I concentrate my fire, I can take one of your Ships o line and do both, or use it as cannon fodder for my sea beggars to close the distance on your other ships. And lets say we have an alternate scenario. I at one point was playing netherlands and was doing rather well on my path to a cultural victory. Problem is, warmoungering Etheopia (who had killed off siam and monty by now, thus controling all africa and the lower western half of europe) felt this was less than sublime, as his tech victory wouldn't be done for another 70 turns. So, he sent a fleet of 3 battle ships, 3 destroyers, and 3 privateers (first time in any game of civ where I saw a fleet of ships and not lone caravels). To defend, All I had where 3 Beggars, 2 galleas, and a city. By the end of it, (10 turns later) he had no navy, I had 2 Beggars, 2 battleship, a privateer, and a destroyer. I used the beggars to quickly snatch up his privateers, which would draw there fire, and allow my beggars to close the distance. If you had 6 ships o line (I'm even giving you a numerical advantage) and even if you where a flawless tactician and won (much less likely now that you can't sack ships) you still would have ended this battle with (optimistically) 3 ships. And when the second etheopian invasion fleet arrived (3 battleships, 4 privateers, 1 destroyer) you would have started with 4 ships (I'm assuming you build a new one in this time), while I started with 7 ships. Overtime, the sea beggar proved to be far more efficient, as it didn't rely on doing more damage to te enemy, it gives more benifit to the player.
