"Firstly, the mechanics of the set make the set difficult to get started with. Secondly, when fully built, Titan Weapons massively overperforms compared to other melee set in almost every metric."
My perception of this was that the game developers intended to reward players for learning how to manage a relatively clunky set. Taking the skill requirements away from sets destroys any sense of pride in specialization, practice, or mastery. I view City of Heroes as a relatively easy game and the skill needed to run Titan Weapons at a high level was something that allowed players to stand out from others.
Having tested the newer version of Titan Weapons I do not see any value-added reasons to play this set over any other set. I believe that continuing to make changes with this style of thinking will lead to a game where each and every character within an AT will play too similarly to one another and powersets will be differentiated only by visuals.
I have enjoyed City of Heroes for the past 16 years, but a game where practice has no impact on performance is a game that I will tire of very quickly.
