It's all practice. When we make mistakes we are dead. Especially versus Witch Doctors. As you already know timing is everything. With wizard we must use the terrain, timing, and our cheap spells to have a reasonable chance. I have found the best spell for wizards is Blizzard. Stack massive damage per hit and ehp. This allows you to simply kite with Blizzard and try and whittle the opponent down. The longer we fight, the more we can wittle down the enemy and storm armour will additionally do it's magic. Then we can use our teleport and wave of force for large amounts of burst damage at the right time.
Attack speed is truly a useless stat unless you are using Ray of Frost. Ray of Frost does huge damage, but has a glitchy hit box and you must stand still to cast it. Use that slot to maximize ehp and dph.
Wiz vs Wiz is actually my least favorite matchup because it's a game of who can get a crit tele or crit storm.
Wiz vs DH is one of my hardest (iria). Spam that blizzard and use large obstacles to block attacks. Let storm and blizz do the damage. Teleport instant WOF can be lucky vs a dh but vs a good dh it is usually a death sentence and should be your last resort or when you easily have an escape route.
Wiz vs Barb. There are many builds. Double disable, Ranged, +ROF 1h stuff. Very tanky low ias? Probably Double disable. If you can get enough base dmg you can play a ranged game with blizzard.
Wiz vs WD. By far the toughest matchup. One mistake, one wrong mirror image and you are toast. I simply play a spam blizz game and wait for opportunities for Tele/WOF and avoid the little piggy shaman.
Wiz vs Monk. My favorite matchup. Blizz around a pole and pray.
All I can really say is abuse terrain and try and out trick your enemy to buy time. Keep him in Blizzard. Don't be foolish and always wait for the right time to tele.
Edit: Also if you have no +Pot or Regen you are asking to lose imo. I have 2 sets, one with 2900 regen. After playing with regen since pvp beta I can tell you it is basically useless unless you are against a very low dps barb. +Pot is by far the best addition a wizard can have. Personally I think a balance between the two is the best option. I have 300 on viles, 300 on bt belt, and can throw a 550 ammy on when needed. the rest of the slots should have +Pot. Easy to get on Boots, Helm, Bracers, if lucky gloves. The questionable spots are on chest. With elite% and Life% it is a hard call. Personally my life pot zuni chest was worth it to me over a different stat.
life% viles. Crafted GL getting armour and regen. IMO viles best because realistically +pot is much better than armour rolls on other gear. Use viles for the extra armour.
Rare gloves. CC, CD, Allres, Int, Vit. If you get lucky grab pot.
SOJ- +2 to blizzard is MANDATORY imo. +7 to ROF vs barb.
Doom hammer or Skorn. A good DH is unique and just does a !@#$ton of base dmg, which makes all of your spells do more dmg. a .9 DH will lie to you about sheet dps and will calculate only 90% of your damage. With our mechanics I believe a DH is better in every situation.
Zuni boots. Pot regen > armour.
BT pants- 290+ vit 90+ int 70+ allres.
BT belt. 280+ int 80+ vit allres armour for dps, or 180+ int, 11%+ life for ehp. Here you will get armour and life regen base so combined with viles at least you have 600 regen.
Zuni chest. Life% Elite% or Pot bonus.
Tal Helm. 180+ 6cc, 70+ allres, Pot bonus 9k+
Tal Ammy+ 6%, 275/275 8cc/65cd. Or crafted ammy.
Bracers. All res. int. vit. cc. pot bonus.
Pox. CC, CD, large int, vit life %. Many good variations of Pox's just make sure you don't forget about ehp on and focus on DPH.
Many other people go BT's combo but I have always felt like Zuni is superior. Not only because it looks better (lol) but because you can maximize your DPH and get very high all res + unique stats (pot) quite easily.
Are you NA? add me and I can show you some good tricks if you would like.
Final edit: Don't forget who you are. You are a wizard and should be proud of that. Every day you will get ganked and frustrated. You will see your fellow wizards, traitors, happily hex+batting you all day. DO NOT GIVE UP. Practice, practice, practice. The day will come when you will NOT regret gearing a sweet PvP wiz.
