Titan is not that difficult. Use same strategies for most the Bosses. Have a healer and use a full scale attack. My characters were in lvl 50 maybe a bit higher by this point. He doesnt do too much physical damage, you just need to watch out for his Quake ability. You should dispatch him easily on 2-3 rounds. All my fighting characters used dual wielding weapons.
