Hey, I started playing the game a couple of months ago, and I run a what seems to be a pretty standard magplar PVE DPS build for beginners: Slimecraw + Julianos + Frontbarred MS + Maelstrom Staff on backbar. Both of the staves are lightning, simply because it's what's dropped for me in my very first Maelstrom Arena run, and you get a free lightning MS staff from questing.
I kept hearing that inferno staves are greatly superior due to burning, so I did a few hours of farming and got lucky with the drops — now I have both MS and MA inferno staves. However, I'm having seconds thoughts on whether spending transmute crystals on all that gear is worth it — most of the skills in my rotation are AoE (Sweeps, Blazing Spear, Wall, Solar Barrage), so won't the 8% aoe passive benefit me more? Also, increased sustain from being able to occasionally heavy attack off balance targets in a pinch is nice. So, looking for an advice from more experienced players. I'm mostly doing solo wbs, solo normal dungeons and occasional vet pug dungeons. Although, I do want to shift my focus to proper group play and start running group dungeons regularly.

And, if the flame staves are indeed preferable — I also got lucky and got myself a BSW set (including inferno staff). I've encountered quite a few opinions that BSW outperforms Julianos, but it's hard to farm and that's why most of the builds online stopped recommending it. Now that I actually got it on my hands without much effort, would Slimecraw + Fully Barred MS + Frontbarred BSW + MA staff on backbar outperform my current setup? Or is difference negligible and not worth 250 transmute crystals to get proper traits on all that gear?

TL;DR
1. Lightning or Inferno staves on Magplar with AoE rotation and sweeps
2. If inferno, what to pair with MS — BSW or Julianos?

Thank you!
