I respec'd lastnight to try out Martial Arts. Did the Bane quests, and decided I didn't like MA much. Brawl just feels right now. Think I'll just dump all my points into it and maybe pick up a 2nd weapon later on.
The limit to six active skills caught me by surprise. I'm guessing I need to look up a fire build. Right now all my points are in immolation. I rush into enemies, explode, and then punch stuff. Works well, but I'm sure it could be more effective.
Did the Halloween bit. I was the highest level at 14. Not sure if they up you power wise but for level 30 stuff it didn't kill me in one hit. We had to reopen the instance a few times, but eventually we got it.
Not really found a use for cash outside of respecs. Glad you can now get items from the NPC mails too.
The Wonder Woman quest levels jumped up a bit ahead of my level. So I took that as a sign to explore, and do Supes/Batman's quests. Gotta say Gotham is way more visually appealing.
