The Ward of Dawn is a truly excellent super, under certain conditions. In PvE, this can dominate/save you and your team, especially when used in tandem with another Titan using Fist of Havoc (looking at this week's Nightfall). In PvP, if you use the super early on, or AFTER everyone pops their supers, it's a great way to shotty it up a notch and generate some mad orbs for your teammates. However, if you're trying to run-and-gun, go lone-wolf, or generally do anything BUT play a pillar-support role, it's uses are severely limited. That's the thing about it being so strategic, though, is that it's GREAT for support, but if you want to do any offense, you gotta change it up. This applies to the classes themselves, I think. From what I've seen, hunters are excellent in PvP, but can struggle (especially blade-dancer) in PvE. Titans are PvP/PvE balanced, for the most part. Warlocks seems to just utterly rock PvE, while sometimes struggling in PvP against Titans or hunters. It's all about strategy, though, and really knowing the tools at your disposal.
