I think the Titan is master race because the ''Defender'' sub-class is a benefit to the player and their teammates. Reasons for this are... while players are inside ''Ward of dawn'' they are protected by anything outside of the bubble plus the ''Armor of light'' bonus which while inside the bubble gives active bonuses towards you shields and gives you increased damage retention, and while outside the bubble players gain active bonuses such as ''Weapons of light'' and ''Blessing of light''. ''Weapons of light'' as said in the name gives you active bonuses to your weapon damage, and ''Blessing of light'' gives you active bonuses towards your shields. Then there is the Titan's ''Striker'' sub-class which when ''Fist of havoc'' is activated destroys any enemy in its path. The Titan's ''fist of havoc'' can be upgraded with these three bonuses... ''Aftermath'', ''Death from above'', and ''Shock-wave'', the ''Aftermath'' bonus makes the ''Fist of havoc'' pulse when it's activated, the ''Death from above'' bonus allows you to aim down on your opponent, and the ''Shock-wave'' bonus allows your ''Fist of havoc'' to travel along the ground.

None of the above. They all have their strengths and weaknesses and all perform best in their own niche areas. That being said, generally speaking- PvP - Hunter PvE - Titan All around - Warlock But anyone can do well in any area of the game with any class/subclass. Just depends on the person holding the controller.

You look cute today

None actually they can tackle other challenges that others cannot. Which is a good thing cause it keeps the balance.
