As everyone around here is I am also unhappy with the new Chrono design.
I don't think that the goal should be to remove the class from certain gamemodes but to make actual tradeoffs.
Here are a few Ideas that I had that would make chrono interesting instead of dead.
Idea 1 Loss: Range -- Gain: Damage and Area Control
Shatter clones to create AoE effects that follow the mesmer.
Example: F1 Shatters your Illusions and creates an AoE on your feet that follows you and deals damage.
Idea 2 - Loss: Instant Speed -- Gain: Damage
Shatters lose the Instant cast, become more powerful and channel longer per illusion shattered.
Example: F2 - Becomes a channel skill that pulses a confusion inflicting AoE around the target. Channel is 1/2/3/4 pulses and .5s per pulse.
Idea 3 Loss: Power -- Gain Speed (Cooldown)
Shatters only shatter a single Illusion but their recharge is heavily reduced (- 50-60%).
Example: F3 - Only 1 Clone may be shattered. Cooldown reduced to 15s.
Idea 4 Loss: Shattering -- Gain: Phantasms
Shatters replace clones with Phantasms.
Example: F1 - Destroy all your clones and summon a phantasm that deals damage to your target. Damage scales with the number of Clones shattered.
