As a result players are afraid to bring in frigates until LATE LATE LATE LATE LATE game for fear of leveling the other players titan too high. With Permanent xp and levels, there is every incentive for a player to risk his titan to kill a ton of frigates just to level it up.
The reason is the game is becoming a giant game of 'don't feed the titan'. The problem is they are not a strong addition for multiplayer. After a few weeks of playing around with them, I am nowhere near as excited as I used to be.
When I first heard about the titans, I was very excited about the concept.
