Welcome Domi_azam. 
Defiant is more then a decent server to level in. 
I would invite you to my SG but as its not very active and relatively new, chances of getting a team would be slim. But there are plenty of other excellent SGs out there.
But, if you are interested in joining mine (The legion of Darkness) Send a global tell to @Thorny Devil, and I'll get you an invite ASAP.
Welcome once again, I hope you enjoy it. 
Welcome welcome
For villain-teaming I find defiant a little more vocal generally, but both servers will always have people around, who will respond to a polite direct tell for team, most of the time.
My alts are below in signature always happy to see a friendly new face for teaming if I am on just drop me a tell
Hi!
I'm basicly completely new to CoV and CoH aside from a week of playing on the US servers, so I thought I'd intreduce myself and ask a few questions while I'm at it
Is Defiant a decent server to level a completely new villain in? Are there any SGs around for the likes of me, seeking mostly (at this point anyway) teams to be a bad guy with?
