I think it’s pretty safe to assume that it’s an intentional aoe skill. Just from the design of the skill, it wouldn’t be consistent or even very sensible for it to not be an aoe skill. It basically is PP with a life drain mechanic built in. It irks me a bit when people just say to do a different build rather than give the pros and cons of a build as I think many builds are sensible in a sense of being very good at doing something in a certain way.
Wiz 3 -> Psycho 3 -> Featherfoot
This class…is going to appeal a lot to those who like the concept of just holding down a button and watching things die. You have three skills by the end of it that accomplish this between Pressure, Pole, and Blood Sucking.
In addition to this, you have a pretty unique ranged grab skill through Telekinesis too. Not a leveling tool by any means, but a potentially good utility skill to get rid of an annoying mob, or if in pvp, you can re-position an enemy while locking them down, potentially killing them outright just from the skill alone, so a very powerful pvp skill, especially when the target has no support.
Of course, you do have some utility with this build too. Raise, in my opinion, is one of the better CC abilities. It can disable mobs more or less while letting you hit them. It also can have some synergy with those with skills that affect flying targets in a special way for party play. This will make the targets immune to ground based abilities though so just keep that in mind.
I haven’t seen Magnetic Force 2.0 (post-buff and fixes), but I hear good things about it, so that’s potentially another good aoe CC ability that does a little bit of damage too.
Really, I think this class has plenty of aoe capability so I don’t think you need linker at all. While you could drop Wizard 3, unless you’re looking to get more CC through Cyro or maybe pick up one of the other high circle classes to put on top of Psycho 3, I think it’s very simple and straight forward as is.
Now, this is assuming you like simple. Some people like complexity and having a lot of options. This is a pretty straight-cut build. You use your Quickcast buff for more dmg and maybe Surecast as well if you think you might be hit by a ranged mob or something, and you use one of your three hold down aoes. Maybe occasionally using Raise for some CC or perhaps even Magnetic Force. So, yes, if you like simple and effective this seems like a good build for you.
This build should also work in PvP pretty well. While many of your damage abilities leave you open, they also disable an enemy or enemies. Raise is a really good CC as well and one that is quick without leaving you compromised. Surecast and Quickcast should prove useful with damage and interruption protection as it’s completely possible for you to be interrupted. A simple Reflect Shield alone can interrupt an otherwise fatal Psychic Pressure so your Wizard 3 won’t end up pointless at all. So yeah, I think this build has synergy in PvP as well as PvE while staying to a theme.
Side mentions to possibly getting Swap or Teleport if you’re into that kind of thing, although for me, I’d want to make sure PP, Tele, and Pole are maxed and Raise is certainly better overall than those other two supports, which really leaves you between Lvl 5 Swap vs. Lvl 5 Teleport vs. Lvl 5 Magnetic Force, to which, Lvl 5 Teleport was a bit underwhelming when I used it (not enough distance). I personally would go with Magnetic Force just to have another CC aoe on standby, will mostly shine as Psycho 2 but might be a good option if other things are on cooldown later. Swap 5 would depend on parties a lot I think as you don’t have any skills I see that really would benefit from it when you’re on your own.
