Hi. I have been warlock and I am level 23. It's come to the point where I've been testing out many builds (mostly for dungeons). For a dungeon builds, is there a really big difference between the frost and shadow builds? I find shadow casts faster but it seems kinda hard to get three spectral orbs in order to use my dragon dance. The frost build seemed better combo wise but slower in casting. Is that all or am I missing something?
