Emp Ssra can be done with 2 (prolly one) Ench - I've killed Emp Ssra with just one other Ench with me (well, not personally killed him - but kept the mezzables mezzed).
I never really used the charm line in the 'old world' unless I was soloing griffons in the Karanas.
But used it more and more as I levelled - doing the 'zeks was so much easier with Charms =)
From what I gather (and I'm probably wrong) about EQ2, without any decent CC it will be inversed of the present EQ - instead of being caster-heavy, it will resort to being tank-heavy, getting groups as a Necromancer will become hard(er) than it was in EQLive, Furies/Wizards will be insta-death chars, clerics will live in fear of casting a heal etc. Of course this is based on the old EQlive aggro system.
The Daze spell I mentioned earlier in this thread does not specify how long the mob is stunned (as Cad pointed out), but then neither did the EQLive spells (until after extensive experimentation), but note that it's from a line of spells under the title of 'Control'? I'm guessing there is still mezz/cc/whateveryouwanttocall it in EQ2, they're just narrowed it down (eg only coercer's can mezz for long periods, but Illusionists can't - both from the Enchanter sub-class). Thus narrowing down the chance of getting a good CC class in your group instead of the regular 'Holy Trinity' (Warrior, Cleric, Enchanter + 3) and *having* to develop alternative strategies to take out mobs (oooooh root-mez!).
Which, imo, can only be an improvement.
