Titan has a specific rotation - LEARN it. Memorize it. You can actually break it into seconds between his abilities. 2 seconds before his ability start running. Put sprint on, use movement songs on the bard. It's doable.

I have FC mates who spend 30$ a year on a proxy service that reduced their latency by 50%, and have had huge success with Titan. Look at your internet connection, who's using it, where is the bandwidth going? Maybe upgrade it?
