Here's a penny for your time. Mayhem is always a wonderful indicator for this. You can tell just by playing which is the most played class but it also allows you to directly pitch supers against another in a live fire exercise. Hunters right now are the top class due to Golden Gun, Blade Barrage and especially Squall and Silence with its "cast it and just go somewhere else" utility. Warlocks are close second with Nova Bomb maintaining it's position as an excellent shut-down super that just dumps damage over whatever it hits no matter how tanky and the Dawnblade being an attack helicoper with extreme airborne maneuverability and heat seeking projectiles. But I think Titans have very little going for them. First of all, Thundercrash. Yeah, it does damage. But not enough. Bungie basically admitted to this when they made the Cuirass of the Falling Star which is nothing but a damage buff. You could argue it's a long range shut down super like Nova Bomb but NB is better because it doesn't launch the Warlock into danger. And the flying and distance traveling is more of a nerf than anything else because you don't get any hyper armor or armor buff during it which means if you want to utilize it to 100% you are basically easy pickings for a golden gunner, blade barrage, nova bomb or squall and silence (something Bungie *also* sort of admitted due to the armor increase from CotFS). Yeah you can use it short range of course but then I gotta say: Why not bring back the original Fist of Havoc then? That was a short range, insta-cast, one-and-done shut down super that worked, Thundercrash if used for short ranges is a weaker version of that. Generally if you play Striker Fists of Havoc is a way better choice than Thundercrash but it still lacks behind other roaming supers in some way or another and the prolonged duration from Trample is alo long gone. Sunbreakers are pathetically weak, while you can make use of the Burning Maul you are not mobile enough to justify lack the low armor during that super. It's also strictly ground-bound and has very little utility for airborne or elevated targets, with the only option for that being the fire tornado. When you go for the Hammer of Sol supers you get a projectile super that isn't strong enough to one-shot some other supers, like an arcstrider (because they sure get armor) unless it's a perfect hit while they can spam their poledancer attacks and the game drags them towards the sunbreaker who is then quickly dismantled through what little armor he gets. You sometimes see Sentinels but they are basically negligible. The throwing shield is nice and the rebound can be useful in tight spaces but other than that they get just steamrolled by most other supers, even other titan supers. And the bubble is most useful in 3v3s with some use in 6v6s and for PvE it recently has been nerfed so people just go back to well of radiance which now once again does the bubble but better. Generally, the greatest advantage Sentinels have is actually the suppressor grenade and this one thing alone is more useful and fun than all the super variants Sentinel has. And you never see Behemoths anymore because they are now slow, clunky, weak and basically a gimmick super that cannot compete with whatever the other supers throw at it. There's probably more I could describe if I were to put the time in, but ey here you go. Bottom line is that whatever a titan super is supposed to do hunters and warlocks have one that does it better. Right now titan supers have no niche to fill.
