Are you a newbie? As it was said before simply play more often and train your gaming skills. Talking about leveling I prefer to level with WoW BfA 8.3 carry. You cant go wrong using these guys, very professional, provided updates and safe. My option was tailored to me and what I had done and they give a bonus for your first time with service. Will be in touch again with these great folks
More practice I think. You can also hire some players to do the hardest part for you. I used to do it and have no regrets about it at all. Happy gaming
How can I be a more effective DPS as a lock in WoW (BFA)?
