Edit: I just wanted to point out that since the inception of this thread, same like with many threads opened before, there was no any meaningful rework for a Wizard class yet in spite of many Wizard players agreeing for once that the class as a whole needs a rework of Powers and Mechanics or at the very least a barrage of bugfixes. This has been going for quite some time now for no reason at all. Wizard as a class was promised a lot of meaningful and beneficial buffs and upgrades to the gameplay which still haven't come to fruition even though we see mods after mods being released, and even though we've seen so far ninjanerfs to our powers followed by Descriptions on Wizard powers being pushed in the patch notes as if they are brand new, yet they reflect a patch from ages ago. Is it possible that someone really hates Wizards so much that they are fond to make the class completely devoid of any fun and usability?
The Wizard community is still awaiting various bugfixes and alterations to the powers which could, at the very least, be more useful, faster or on-par with other classes that already enjoy such benefits.
Compare Steal Time and Bane. Which is a better and faster AoE power? How many times can Bane be used?
Compare Steal Time and Smoke Bomb. Whish is a better and faster AoE power? How many procs can Smoke Bomb apply?
Now, Compare two of powers.
Bane + Bane. Extremely fast and superbly potent. Possibly best AoE power in the game. Only downside is Divinity refill in a prolonged fights in Dungeons. For easier content, it is absolutely crazy good. Easiest thing to use in the game.
Smoke Bomb + Path of the Blade. One is do a bit, other is do basically nothing at all, and still deal damage. Rogue right now is a DoT master, more so than Warlock in many scenarios. Bleed + Toxic Blades? Completely wrecking anything in its path.
What can Steal Time do? Hit enemies at the very last proc, meanwhile both Smoke Bomb and Bane killed all enemies to begin with. Bane was cast twice, and Path of the Blade was already cast on Rogue and by the time Smoke Bomb finishes its animation, Rogue is already on the next group of enemies, applying Bleed. Both Paladin and Rogue are naturally fast classes, too. I don't mind the speed of the Rogue, but a tanky Paladin being pals with Speedforce is a bit weird.
Meanwhile, Wizard used Icy Terrain and Steal Time. Since Chill is bugged, and since Striking Advantage doesn't work without CA, that pretty much means that Icy Terrain is practically useless in AoE combat when compared to both Rogue and Paladin's AoE + DoT potential.
For the maximum damage capacity, that naturally comes to both Paladin and Rogue without much effort, and lingers on the enemies since it's not terrain-based (meaning that enemies mustn't remain on the Icy Terrain for the effect to Apply), this allows more movement, more agility, better organization and easier combat. Meanwhile, Wizard needs to keep the enemies on the Icy Terrain for 6 seconds in order to get full benefit of the Encounter.
How many times can Bane be cast in 6 seconds? In 6 Sec Smoke Bomb already destroyed everything.
This means that Icy Terrain can be reasonably used for not more than 1 to 2 chill stacks in fast groups, leaving Steal Time's activation for the later.
Both Striking advantage and Chill do not work, meanwhile all DoTs by both Paladin and Rogue will work to their full capacity with the only downside being - not critting sometimes, due to the way the game works now since MOD 16.
