While I hate defense bonuses in fps games like titans super I must admit without it the titan would have the weakest super of the bunch.
That said I would ideally like the defense boost removed and the super buffed in some other way. Besides, the trait for the defense feels like a crutch when it should only be one of many viable options.
Well that's why I'm asking for slight nerfs, not asking for them to completely remove the defense bonus. Also, with the Golden Gun harder to use, the supers will be much more balanced.
Additionally, the Warlock and Titans have extremely good Super upgrades while the Hunter doesn't. (Level 20)
