You are fighting against windmills. These devs have a very narrow and limited vision of design, and anything that falls outside of that vision is consigned to oblivion.
Their vision is that the wizard should be a DC caster IK/CCer and nothing more. All spell dps, including negative spells, for the wizard should be more about flavor than effectiveness. I wish I was wrong about this, but these devs have repeatedly shown that they don't care about wizard problems outside of DC casting. What does it matter that there are more and more immunities and obstacles to IK and CC.
Dispels should be effective, and npcs should have larger cooldowns on certain spells. But this will never happen. Debuff spells, which are absolutely useless currently, should be able to affect bosses. Why do the only useful debuffs have to come from sources outside the class like epic weapons?
Spells that the devs have stolen from the wizard list, such as weird, time stop, evard's tentacles, and confusion, should be entered into this list to which they rightfully belong, even if they continue independently in their current sources. But not. The devs don't care about the versatility of the class whose strong point should be versatility.
If they haven't even bothered to create arcane tempest scrolls. The perk for spontaneous VIP casters? It works for them. The perk for prepared spell casters? It doesn't work, of course.
The devs don't care. They won't do anything. They've had years to do something. We have begged them during the ED pass to introduce some changes for non-specialist casters without bypass. They have done? Of course not, they didn't even deign to reply that they didn't want to do it.
They don't worry. That’s the reality. Wizards do not fall into its stereotypical, constrained, squared-off design. Wizards need a different plastyle that they don't approve of or understand.
edit: upvoted, but it won't help. The devs will ignore this topic. They always do it.
