I'll admit it: I'm about to get piled on. There's gonna be a lot of disagreement here. I've had too much to drink and I feel like making an unpopular opinion thread.
Sencliff, while awesome in its own way, is IMO far from adequate as a headquarters for team evil on the surface. The system on Sencliff rewards a very high sail skill and land pirate is very much something that is hard to put together. I've seen the popular wisdom of "Be the change you'd like to see" slam head first into powerful in-game incentives too many times to entertain it any further.
Your typical good player in Skal has lots of options. He can join the radiant heart or become involved in politics or law enforcement on probably 75% of the server's land mass. Your typical evil player on Skal has two options: Pre-arrange for epic skill focus in Skal and accept a mostly conflict free life of circular sailing against NPC mobs or take a slave collar.
Sailing is fantastic in its own way and the hub can be a lot of fun, but it feels like bad guys are being redirected to remote corners of the game world where it's hard to generate conflict without a rare slave harvest or DM approved raid. I think we need some kind of bandit camp, necromancer friendly settlement or something in that vein. Preferably in a higher level area to reduce incidents and accusations of real or imagined griefing.
It feels like a full time job finding people interested in pillage and plunder and RP based antagonism. Sailing in circles and talking about shop profits with underdark schemers does very little to build tension and create panic on the surface. Once you leave Skal, being the bad guy feels sad and boring.
I anticipate massive disagreement but I'm a big boy and I can take it.
