Yea, the problem is, you have to stand still for 2,5 sec. (which is an eternity vs. a good sin) to cast pest. blast, then hope for a crit to get insta Ice strike, then hope for a crit on PB+Chill detonation and Ice strike as well and then hope the sin is actually dead, because your next crit will most probably activate LO again (also god forbid his Dull Pain is available).. I´m not saying it´s impossible (got some nice crits on Elec´s sin as well back in the days), there´s only too many "if" and a good sin with all CDs up still has like 90% chance killing you within few seconds in an open terrain (9% are your chances to run away and about 1% to kill them if they noob out )
I mean, I´ve started a sin 2 months ago, got some solid PvE gear meanwhile, but still almost none PvP relevant AAs (invested heavy in PvE side, like -aggro, TW/FH etc.), but even as a PvP lvl 0-1 nub I´m dishing out so much damage it´s not even funny... ok, it actually is, 4k detonations and 4k DWW on running by targets won´t get old any soon, I guess Of course, I can be burned down like paper with my current 6,8k HP (without healer buff) and almost zero armor/protection, but in a minigame with less individual focus and responsibility as Jhebbal Sag, I can still get some solid KD while ninjaing flags (and hunting totems ), where half of my deaths are as the result of my still low rank AA antiCC.
Also note, that I´m writing this as someone who hasn´t been in minigame for almost a year till now (got bored with PvP 10 necro and no new PvP content for years), is playing his first melee PvP char (some lowbie minis on DT back in 2008 don´t really count) and is not even close to those PvP gods I know from Aquilonia/Fury etc., who know every single class ability in the game and how to use/negate it even when you wake them up at 03:00 in the morning
TL: DR
as a caster meeting a solid sin, you better hope you´re dressed nicely enough for your funeral
Really? Necro got basically 1 solid CC he can count on and that is his ranged stun with 0,5sec. cast time when feated (and that can be still resisted with sins LO). Some others that can be used are his fear (quite obvious to see and jump out of reach, but still nice to use on nubs who jump you from back when on SW and react too slow while being too confident about them killing you easily) and frontal cone root, which is okayish.
Snare got nerfed hard, still got short range, but is not instacast anymore and the target is almost at your position when the cast is finished. Also I´m yet to see someone using the pet consuming fear after that nerf.
That hideous frozen hatred snare is imba idd, but you must get fatality to spawn him and then keep feeding him with fatalities so he doesn´t despawn after 1 minute. This is not that hard in minigames, but in 1 vs 1 situations you can´t count on him at all.
And then we have the pinnacle of some FC class designer mastermind, the AoE stun after using Tome of Epithur with it´s unique 15 minute cooldown (well, only 12 when fully perked), 3 seconds cast time and.. bah..
PS: damn, this post got quite long in the process..
