Everything has been said already. The Titan currently has the strongest super in the game, with the highest kill potential and the least possibilities of retaliation. You say yourself that you don't like the PvP, so you obviously lack the countless hours other people have put into it, to understand the full set of dynamics. If you still don't understand why a nerf will come, nothing anyone can say to you, will change that. Just like the Thorn, TLW and the Bladedancer weren't OP according to their abusers, they got a nerf nonetheless. The Sithlord has one issue: he needs to get much closer than the Titan. Until the Sithlord is in DPS range, the Titan already annihilated everything.
