Any clan will do? Don't try Enigma, DirtyWorK is much nicer :P But on a serious note you should choose carefully. What do you like? Casual playing? Lots of PVP? Role playing? Big clans or community clans?
There are a number of big clans, Enigma is new to me, but seems to be big. You have WAR, strong PVP and DRACII. Then of course you have Einheit (don't join them they suck :p) ... well for now Einheit rules the server. Then you have medium to large size clans Sentinals, Pirates and of course my fav clan DirtyWorK. It also depends on your nationality perhaps, the Pirates are mostly Greek and I think they are casual. DirtyWorK is really International and we like casual role playing. Sentinal, well don't know much about them, they seem to be PVP oriented with I think two nationalities (see their description in community). There are probably more mid size clans, but I don't know. And then their 100 or so small clans, some are in-active...
Ha ha, well it's just that i'm from Bulgaria and once i had bad expirience cuz of that but nvm. English is the one i use mostly, i understand some of other langs mostly slavish...
Aaaanyway that's great info, and i think DirtyWork is the one for me, since it's mostly casual, and i hope i'll be in help with an arbalester cuz thats my fav type XD
Bows are always difficult. But your class doesn't matter to us really, active players are always welcome. For joining DirtyWorK you can always contact our leader directly: bretthart or my toon BerenRuyter. Think about your choices.
Deathadders and their alliance is working on becoming quite a force, thats exciting also of course. Big battles with leading clans... every clan is different with different pros and cons
