The Titan is a massive siege weapon. Units will do the most damage to it espiacially archers as the titan is slow. This Rec game illustrates how microing your titan can win the game.
Slight skirmishes in classical when everyone is aiming for Heroic. Player 1(blue) sends an army to teal who is practically dead by half game time and resigns. Player 3 builds a titan along with Player 1.
Now comes to the micro part.
Player 3 sends Titan to Player 2 crushing as much buildings and towncenters as possible.
Player 1 finishes Titan and tries to make Titanomachy.
Player 1's titan follows the map without attack move( moving in the sahara desert) or being attacked while moving.
After there are no Tcs to destroy Player 1 and 2's eco is destroyed leaving only player 1's titan with 5% hp left.
Player 3's army destroys any units of player 1 and 2.
Leaving player 3 and his eco left. Titanomachy comes with 6800 hp of player 1's titan and 6900 hp of player 1's titan.
An army comes along to help assist player 1's army.
Player 3's titan wins with 1400 hp left.
Since Player 1 and 2's eco is destroyed the titan comes up and destroys remaining resistance.
1) titans are like seige just like u said but sending archers to seige is just plain stupid their best defence is against archers.
2) TITANS ARE QUICK i dont care what ur game shows, titans just look slow cuz they are so big but put them to a test. A titan is just as fast as a hippikon. and thats a greek titan, put it up against the eggy titan(the fastest) and see who wins
3) TITANS ARE LIKE BUILDINGS MORE THAN LIKE SEIGE crush attack completley ditroys them
