Guild Wars 2

Yea I tried a grenade kit spec but just didnt like always pressing the 1 button to cast the nades. When I check the fast cast all it does is cast at my mouse but I still need to press 1 everytime

This is my first post so im not sure if this has been covered before but ive noticed that grenades have a auto attack under water but not on land, is there a reason for this? would it make them over powered?

also im doing heart quest and tactician lyan gives you a grenade pack to test that has different skills than the normal grenade pack.

IE. flame grenade, fear grenade, and glue grenade.

id much rather have those skills on the bar would this be considered as a change to the kit please!!!
