Ok, so... if you like pub dueling, this one will be very fun for you. As for your 1st question, I prefer ES Light sorcs since you will already have massive +light skills to utilize, although a pure light sorc with maxed synergies and blocking is very effective also, when equiped right.
With an ES build...
Stats
Str - As high as you need it... always the same for PvP nearly... depending on how you play and what skill you use it will be different. If you choose to play something like lightning which doesn't require FCR as much as something like CB does than you could use something such as Gladiator's Bane, which requires 110 str or so I believe... otherwise you can go for a Vipermagi, which works well with Dmg Red, Res, +skills and FCR.
Dex - This is tricky, it will either be base, or 75. Base dex is for all builds not planning on using wizard spike, and obviously 75 is for builds that will use it. Wiz is useful if you need to hit a FCR BP or would like the big plus to mana. It also helps with res, although they are not very important in a solid ES build.
Vit - None, either way nothing... with this build your health is all in mana...
Energy - Everything else, I suggest filling out other stat requirements than just piling it up in here until your finished lvling. Since this is yoru life in this type of build, you need as much of it as you can get.
Skills
Telekenisis - 20 Points (most important)
Energy Shield - Adjustable (will explain at bottom)
Lightning Mastery - 20 Points
Lightning - 20 Points
Charged Bolt or Chain Lightning - 20 Points, your choice which comes first, you will end up filling the other at the end of your build anyways.
Energy Shield - This skill varies... think of it this way... you need a lvl 40 ES, if you have perf equip such as...
9 ES staff
10 Light GC's
1 Anni
Vipermagi
Arachnid Mesh
+3 Lightning Ammy
2 Sojs
Shako
These are all the items that will add to your skills, giving you a total of +29 ES, this leaves you with a lvl 11 ES, saving you an extra 9 points if you didn't do the calculations before hand. If you find a nice +3 Light skills Circlet than you can use less... just determine your final equip and than go from their.
Equipment
As mentioned above that equipment works well, along with that, your other "perfect" equip would be...
Frostburns
Silkweaves
And since the gear above was only for a prebuff...
Heart of the Oak
Lidless Eye
the HOTO is under dispute, as said above wiz also makes a nice alternative. Or a nice +25% Lightning Damage, - 5% Lightning Resistance Eschuta's is nice as well, its just like HOTO, but doesn't have the res, although it does more dmg, a better choice for chars dealing physical damage. Another alternate option is a Griffon's Eye helm, this will take away one +skill point, but will give 25% FCR and more light dmg, it can make a nice difference if used, though a good one is pricey.
As you can see this build isn't way too expensive, the GC's is all that may kill you...
No ES Light Build
Although this is not my specialty, it is mostly the same... this sorc will max all the synergies instead of maxing TK and ES. The equipment that would change would be things like....
Frosties --> Trangs Gloves
Vipermagi --> CoH
+3 Light Ammy --> Maras
Lidless --> Stormshield
Most of the other equip should still work well, it is just that this build is less mana dependant, so for skills, put many more points into Vitality, and try to avoid putting points into Energy at all, since your Soj's, Arach's, and Silkweave's will still add a ton of mana for you...
I'm pretty sure that's all you need to know, if you have any more questions just call my name.. or find me at *Vesti *Vesta *Sartok on USEast Ladder or NonLadder. :thumbsup:
Thanks for having faith in me, I hope I helped
