Blizz/meteor never had/dont have any cooldown on "official sources".
The root you say should be implemented reeks of idiocy, why on earth would u be rooted to the floor after ur spell has been cancel'd?sounds to me like your just after an unmolested window to kill a wiz.
The only reasonable way for a wiz to tank the mobs ppl are saying is if those mobs are slow/cursed, from personal experience i can tell you that slashers can kill me in 2 hits as can tortured souls in hell.
TDB has never had a cooldown, sdash has the same cooldown as on euro, so whoever posted that, im not sure what ur talking about here.
As for people saying that wiz are suprmeley OP, i suggest u play ur class a bit better,
Ask kingtony how to deal with a high lvl wiz on an archer.
Ask Aso how to deal with high lvl wiz on an tao.
Ask toriblack/manbearpig how to deal with a high lvl wiz on an assasin.
Ask depress/hyper/alfie and a few others how to deal with high lvl wiz on a warr.
as for wiz vs wiz, im not gonna help u, not cos i cant, but because i dont want to.
Now, you say MB is OP...add the mp consuption that should have always been there, and then think about the damage increase u actually gain from it.
look at level 3 rage and lvl 2 MB and consider the damage increased gained with each.
With lvl 3 rage on a dc 100 warrior( fairly easy to get) ur looking at a 15ish dc increase which equates to (around) +15 damage x2 for tdb and +40ish damage for fs.
With lvl 2 MB i get mc 18-18 which equates to about +20 damage per spell and a raised average for Flamefield with + 50ish damage
rage has no cooldown, MB has 20 second cooldown so as u can see at lvl 50 u gain quite a similar advantage on a warrior and wizard respectively, but i see 0 complaints about warriors being able to near 1 hit me at lvl 50 and near 2 hit ANY OTHER CLASS.
You say that a lvl 52 wiz can 2 hit a lvl 52 warrior or somthing to that effect? thats idiocy, you know the mechanics of the spells ur talking about, there are 2 ways to avoid this on a warrior..stand still and reduce the damage by half or simply dash out of it, u know u can.
Now, poeple are saying other clases die in 1 hit, obviously u mean 1 cast, but u can see that this is only achievable in 1 way and if you let a wizard put u in that position u should get floored for not thinking about what ur doing. you know what it takes to stop a wizard from using blizz/met
Basically what im saying is this, alot of this OP ness ur talking about is down to YOU not playing ur class with any forethought as to whats needed in any given circumstance, you can see that ive mentioned a few names of ppl who do.
