I have seen titans pretty much solo the lamps on hard and not take a shortcut. I soloed it the other day with mine its actually fairly simple if you can change stuff quickly. I run spike grenade and the saint helm to pop a blind bubble if needed and once I get to the end hit the plate jump on the rock change to no back up plans quickly so my bubble lasts longer then when the ogre starts shooting my way pop my bubble stay in it till the bridge is built then run.
