Guild Wars 2

What if, instead of being random, Elixirs involved rotating images over your characters head when used, requiring a second activation to choose your effect and use the skill. The process would be similar to the “Pick a Card” skill used by Twisted Fate in League of Legends.

Step 1
Removed random effects from Elixirs.

Step 2
Reworked the way Elixirs function. When you use an Elixir skill, you hold on to the Elixir, “cooking” it like a grenade. Images rotate over your head, signifying which effect(s) will be created.

Step 3
Significantly buffed Elixir effects to compensate for the increased channel time and increased skill requirement.

Remove HGH trait and replace it with a new trait which grants the effect also to your nearby allies.

I suppose channeling for both self and thrown elixirs would be awkward.

What if thrown elixirs became an object that you could target, with a rotating, effect-denoting symbol over them. When they reach the effect you want, you can attack them (one shot) to release that benefit to allies. No need to remove HGH.
