Am I the only one that thinks the cast time of crystal blast isn't really 1 second at all? I mean, the first shot of Crystal Blast takes so much time to cast - then when you cast again, consecutevely, it feels like it is 1s.
When I get bored, I like to test builds, unusual skills and stuff, and Crystal Blast is a pain to use, I felt really frustrated while using this skill, that is supposed to be a "spammable" AoE. When I was in craglorn, doing Anka-Ra this weekend, by the time that I finished casting my first Crystal Blast, the "boss" (the gargoyle statue that slowly walks towards the NPC) was already with almost half of his hp - and I was in a team with 2.
Not to mention that everytime the mob dies before you complete casting, and if it's a first cast, not a sequential cast, it feels like it takes forever. Also, when the mob dies, you have to cast all over again and you lose like 2s/3s recasting crystal blast on some other target, the casting feels really delayed.
The devs should test this skill tirelessly, as their main spammable ability, so they could see what they are doing wrong.
Anyway, IMO this should be a spammable ability (while frags is the proc ability), with no casting time or with reduced cast time by half at least.
