Stop going off topic and trolling with the drug talk. Its well known that LSD in wow terms is lock/shaman/druid.
Any more bans will be handed out.
To the OP LSD is one of the best comps right now its pretty brutal. You wont be purging that much, majority of the time will be nuking. You will be thunderstorming and earth binding to peel and throwing heals when needed. But apart from that blowing up things is your main objective.
