Which to choose?

So I have returned to COH after 3 years away. My intention was to always play, but WoW and real life got in the way. But I forgot how much fun this was. So this is my dilemma. I made 3 WP scrappers, a katana, a BS and a WM. I have leveled all 3 into the mid teens so I could check them out. I like the katana graphics but it seems low damage compared to the other 2. The WM is awesome at this level but I don't really like the knockback. The BS seems to be a good compromise. I plan to mostly solo as I come on at odd times. Which would be the most capable at higher levels. Also which pool powers would be the best choice. Thanks in advance for any responses I get

I'll second Kat/WP. But, it's strange. You shouldn't be seeing any knockback from War Mace. They have a knockup and a couple knockdowns. Other than that, it's mostly stuns.

KAT/WP hands down mate. This will turn into a powerful and more importantly FUN toon to play.

Ok cool, thanks for that, I will level the katana scrapper. What about pool powers? What would be a good choice on that?

Body mastery hands down for that.

My personal choice between those 3 would also be Katana. Your attacks may not hit as hard, but you do them faster, which in the end gives more damage potential when you're fully built. I never liked the slow wind up animations for BS and WM.

You may know this already, but clicking "F" auto-follows your target, which helps a lot with knockback.
