Succession Wizard PVE has gotten some decent buffs recently.
Depending on spots now succession wizard is not a bad class to grind with, of course awakening spec is still lower effort for similar results.
I personally prefer to use Voltaic over bolide of destruction for pve as its faster, has self cast speed buff.
Lightning Storm and Fireball Explosion just provide reset on the 2 most important addons.
Blizzard after the changes is pretty good DPS skill and these addons just give it more dps overall.
Concentrated Magic Arrow addons passover to Earths Arrow skill and just gives a general speical attack damage boost.
The Voltaic cast speed stacks with the addon.
