I've played Warden since the Morrowind launch because I loved the original game that came out before a lot of current players were even born. I'm a bit older. 8-) I really fell in love with the Warden, but its been nerfed into Oblivion.
The most enjoyment I had playing it was when I ran offensive/front bar Sword and Board. I was able to Sub-Assualt>Cliff Racer>Shield Invasion and it made an effective combo for the class. It was a bit tough to line up as it required 3 seconds to pull off, but the delayed burst damage with a Stun was manageable to pull off in the chaotic nature of pvp, Stunning or Immobilizing with any of the other Warden options are not effective at lining up the Sub-Assualt, with a Cliff Racer being cast at range. A gap close helps line up the Sub-Assualt attack as its easily avoided other wise, and the Stun held my opponent in place for 1 second while they broke free so everything could connect, and ta-da a viable delayed burst combo that worked. Swap bars to execute or repeat as needed.
Giving Warden back penetration on Deep Fissure was definitely a step in the right direction. However I've watched extremely experienced pvp streamers fail time and again on getting that skill to line up with a D-Swing stun, not to mention to play warden in that way you can't cast your Cliff Racer at range, which is the classes spammable dps skill, not D-Swing. So many classes are just build around D-Swing that they lose class identity. They literally become D-Swing builds that the class supports not the other way with D-Swing supporting class skills. I could use Sword and Board again, but its lack of base penetration and damage in comparison to Two Hand or Duel Wield still puts it behind them quiet a bit in damage.
I believe a great idea to revitalize Warden would be to change one of the Natures Grasp morphs to be a Gap Close Immobilze, with some other added benefit to it like a dot with a hot similar to duel wields skill Blood Craze, or Shield Invasion's base damage, something along those lines. A new Warden pvp identity combo could be Sub-Assuat>Cliff Racer>Natures Grasp and it can effectively be used with Duel Wield or Two Hander. 8-)
