sorry xD must have been hyped on coffee

missed the first part of your post

well my good posting stands :p

light line

strong single DD
very mana efficient single target nuke

nearsight
lowers the targets range to cast spells/shoot arrows.very good for rvr.

dex/qui debuff
lowers the attributes for faster castspeed/swingspeed

aoe mezz
mezmeration spell.low duration,but can be handy in smallgroups/solo.

the light line is a very good strong choice for rvr.with the rest points into mana you still get disease/snare nukes with the same effect(just lower duration/damage).



mana line
single target snare dd
slows the enemy movement untill other damage is applied or the snare timer runs out.rather low damage/castspeed but is very usefull against melee classes.

aoe snare dd
slows multiple enemies in a small area.low damage/castspeed.can be handy vs multiple "tanks" (melee classes).

pbae
aka bomb. highest source of castdamage in the game.deals a lot of damage to everything around you. the further you are away from the enemy the less damage you deal.can be great in combination with stun.

s/c debuff
lowers con and with this the maximum hitpoints of the target/s.

disease/aoe disease
slows the target down slightly and the more important part is that heals on the target only heal 50%. very important for rvr.(a low spec with your leftoverpoints is enough to use these spells aswell.just the duration+ mana cost goes up here)
-
mana is by far the most popular line for pve. the different spells are all strong for rvr aswell.



void line
bolt
a long range "nuke" with a re-use timer of 20 seconds and very fast castime. along with the baseline bolt you can use 2 bolts.

aoe dd
simple area effect dd. damage ain´t that good due to the nature of the spell. can be handy to kill multiple pets fast or rupt multiple people.

gtae dd
a groundtarget spell. reuse 6 sec.
is a very good tool in keep sieges (can cast without line of sight). or to "pop" stealthers.

resist debuffs
lowers the enemy resists to the element you debuffed.
so spells off that element last longer and deal more damage. kinda handy if you team up with other casters.
-
void is just good for keep sieging and standoffs. both are not that common.the lack of a decent single target dd making this spec almost obsolete for group rvr unless you are using the debuffs for others.


i reccoment to spec mana for pve. then either stick to it or respec into light later. up to your preferences. a general thing about the eld for rvr is that you don´t just stick to one thing. you have to know when to snare/disease/nearsight and when to deal damage and not focus on one thing too much.like most casters you highly specialize into one "spec line" and put the remaining points you with mini-ups (lvl40.5 etc) into another one.
the void line is nice for sieges and standoffs, but pretty crappy on open field.so most people use either mana or light spec for rvr.
