I'd wish Darkside and Living Shadow got expanded upon a bit. It feels like there was supposed to be something there that was taken out before release. There's a new job gauge with both of those timers on it even though Darkside barely needs a timer and having a timer for Fray is pointless. It's like there was some planned interaction between the two and I hope whatever it was, we'd get that in 6.0 because at least for me DRK is a "resource management" tank and I'd like to see that side expanded especially since it looks like something like that might've been in the works but just got canceled.
Regardless of the above, I think something we should get (and could get in a patch right now) is the ability to sic Fray to make him switch targets. MCH Queen has the same problem. Make the summon button a sic button while they're out or add another separate button for it. Kind of minor but quite annoying when you'd actually want to have them switch targets.
Delirium seems like an afterthought and is one of the few things I dislike. I just don't feel like adding another "press the same button 5 times" burst on the one old tank that didn't already have that is a very imaginative or good idea. There has got to be a more interesting burst design out there. I'll deal with Delirium for ShB because while it's dull it's at least not clunky but I really hope for a redesigned burst come 6.0.
Living dead.. yeah. Every patch I'm waiting for a change and I truly hope we don't have to wait until 6.0 for it. It's especially jarring when WAR Holmgang keeps getting fiddled with. Needing a target and locking you in place is clunky? Let's take that away. Oh you can't take 3 Titania tethers or all 3 Titan stonecrusher hits with a single button like other tanks? Here's a couple of extra seconds for you. I'm glad for Warriors getting that but our invulnerability still KILLS US. I honestly can't believe were still dealing with this.
