In the first months of USKO the 2 players i had the most respect for were both archers with the same skills/limitations as we have on this server. Their names were Gambit and Trizzen... Both of them had permanent PK symbols, both of them were awesome players (and thats prolly why they could handle playing archer), both of them did both solo and party PK.
I will admit that a solo archer mostly has to KS his kills but my god are they KS machines if played by someone good.
Also... a really good archer is 10 times more welcome in my party than a good sin.. Archers can actually take a priest completely out of the fight and they can keep low HP enemies from towning and getting away.
Adding a stronger bow might get more people to play archer but only the best of the best will ever be scary as archers. Trizzen and Gambit had IronX +7 and strongest merchant bow +8 when they did their ownage. So i dont see why archers cant do it now...
Im thinking its just a lack of skill/brains with new KO players :P
