If you're finding your damage is low on Titan then you need to learn his pattern a bit better because I figure you're not fully utilitising your abilities. Knowing when you can and can't use Blood for Blood or jumps for example, it makes a big difference in that fight. I tend to not use jumps when Slides/Weight are next in the rotation, and wont use blood for blood if tummult is coming, it's just a case of knowing exactly when to and not to do stuff. Generally though, you should never stop attacking except for the short period when you back away from a landslide, but you could use a range hit then if you want to, I tend not to though because I would rather not drop my combo.
