Guild Wars 2

I would like to give my opinion about this change.
Perhaps Mimic was an understimated ability, however it was really useful and perfect for certain fights/situations (also it has a good synergy with Retaliatory Shield -Trait-). I still remember its benefit:
- Just after release, an extra reflection was very helpful in my first dungeon runs (it saved my life with the Giganticus Lupicus Fight)
- In the Uncategorized Fractal against the harpies
- At Southson Cove, against the Karkas
- In the Queen’s Gauntlet, against Subject 7
and many other times..
Maybe there is some other reason behind but did you really need to change this skill dramatically? You could simply add a new utility skill rather than replace it (obviously along with others for each profession). So.. I have a proposal.

In the future, when you add new utility skills, could you re-implement it (with some changes if needed)?

I suggest my version (works similar at Illusionary Counter/Illusionary Riposte):
New Mimic = Illusionary Shield – Reflect all projectiles. After a projectile has been reflected, the remaining duration will reflect all projectiles and block all other attacks. (Duration 4 seconds)
Echo – The Illusionary Shield explodes for low damage or bleeding (Combo Finisher: Blast) [It can be activated if you press the button again. Activating Echo will cancel your channeling.]

I will miss the mysterious sound when you have the Echo activated ;(
