Wizard in Rebirth "Beta"

Lady_Selan - Sanctuary

I just reached level 70 not long ago and excited of my new TT70 wand. I am concerned about how much defense, HP, and powders a wizard with arcane gear need to live through the challenge. I want to avoid going LA if I can but many players don't want a wizard unless he/she is LA build. If needed, I'll refine my gear more if I must to make up for my weaknesses.

I have about 2.5k to 2.6k hp buffed and 11k to 12k MP and possibly over 2k (won't push it to be 3k) physical defense with every buff (BM, Cleric, Stone Barrier). All I really want to know if from experienced wizards that this will work out in beta. If not state what is missing. Thanks in advance.
