Um...anyone know?
The best I can give you is:
www.nofuture.org.uk
And go under the City of Heroes tab.
Hero Builder
Good program. Has what you are asking for and you can check out builds in it.
http://www.paragonwiki.com/ and http://www.nofuture.org.uk/coh/ and http://www.nofuture.org.uk/cov/ and http://coh.coldfront.net/ and many others.
Is there a site out there that has all the information on each power in the game? like how much end cost this power has or how much damage it does, etc?
