Very impressive. I just watched the first video, but I’ll be getting to the others tomorrow. I hadn’t bothered to give the focus the time of day due to the defensive nature of its abilities, but I hadn’t really considered the combo potential it provides nor the sheer damage that warden puts out!
I was also a bit surprised by how well you viewed the greatsword. I had always found the damage output severely lacking (note: pre-buff), and while mirror blade is wonderful, it didn’t make up for the otherwise lackluster performance. The point about the berserker effectively taking the melee hits for you is an interesting point of synergy, though, so I’ll definitely be giving it another shot, particularly with that buff.
I fully agree on the staff, though, and I always keep one on hand for the reasons you listed. Honestly, the quality of support chaos storm grants in the big boss fights is completely unrivaled, often outclassing elite skills. All it needs is someone to provide the Blast to give everyone chaos armor, and the situation quickly turns in the players’ favor. Add in everything else the staff does (particularly those condition-inflicting clones!), and you’ve got an obvious home-run weapon.
I still enjoy the scepter, though, as a shatter-heavy build can very easily spam out Mind Wrack or, even better, Cry of Frustration with alarming frequency. PvE mobs will often kill off a clone or two while you’re auto-attacking, which slows down clone production from that enough to allow for the shatter skills to recharge. CoF combos very nicely with Confusing Images, and I will have to respectfully disagree with your analysis of PvE mobs not being reliable enough on triggering confusion. With CI, you will almost always get a trigger in, and oftentimes two. Five stacks of confusion usually results in more damage than the five hits of the beam itself from a single attack, so two attacks can mean death for trash mobs.
I also want to put in a word of support for the blocking skills, both scepter’s 2 and sword’s 4. They effectively give a blind, deal a good chunk of damage, AND create a clone! This means that pairing the scepter and sword allows you to 1) land five stacks of confusion, 2) block the next attack or two while still dealing confusion damage, 3) deal one or two counterattacks worth of damage, and 4) shatter your clones for the coup de grace. 1 on 1, it’s a good way to clean up.
I won’t say the scepter outclasses the mainhand sword, but your video ranks it as the worst mesmer weapon available (and hey, something needs to have that title), and pre-buff, I would have given that title to the greatsword. It’s still a build-dependent weapon (straight DPS the scepter is not), but perhaps a touch underrated.
