It's more risky as a Warrior obviously, but that makes it more fun to me. I mean, I wish I had a healer to pair up with then things would be bananas but for me it's all about helping my team so I'll try to peel off people chasing my mask carrier with grapple and then snare them with that razor blade ability (forgot what it's called). I also try to jump in there first so I can get the attention of the other team while the rest of my team (hopefully) uses it to their advantage. If things get dicey I'll leap away. So far this has worked really well, I don't die often and I end up with a lot of assists.
The few times I've managed to go one on one against other players, I usually come out on top if I have all my abilities ready. If I just had my 8th and final ability slot, it'd be so much better, ugh!
