I actually registered just to post about the downtime changes. My points, I'm sure, have already been made by other people, but I just want to make sure they are seen. My concerns center mostly around the low-mid level shaman, which is very important if SOE indeed nets more new players with these changes, as they have stated.
1. This kills root rotting as a "growing up" tactic. I know high-end shaman don't make much use of it, but many that are below 60 do. I just came back to EQ from a 2-3 year hiatus, and am rolling up a fresh shaman. Root rotting was the absolute most efficient way for me to solo all those years ago, and as soon as these changes go live, that won't be the case anymore. It will always, always be better to blow through the mana and sit, especially if you can time it to where your buffs fall at about the same time your mana reaches 0 (at earlier levels, anyway). Grab some pine, med to full in 3 mins with no hp loss due to canni, grab a beer, buff back up, rinse and repeat. Why wouldn't they? You are far better off doing this, especially if you have a larger-than-you-should mana pool for your level. So out with the old "just give me a puppy and some ac" shaman, and in with the "OMG Acrylia and wis rings ftw!" generation of Shamuids.
2. DogDog tanking a slowed mob while I sit/canni. Pretty much the same as above. Mages and Necros will be in the same boat, and will have to blow through mana to kill the mob so they can sit as early as possible.
(The first two here really illustrate a larger point: If these changes do bring in "new players", those players who make casters will all, regardless of which caster they make, "grow up as wizards". This could be a very bad thing, IMO. You will have a ton of shaman/clerics/druids running around with max evocation, and crappy everything else. Why heal after a fight when you can just sit for a bit and get stupidly fast regen? Furthermore, why even bother memming regen spells? The fast leveling shaman will have 3 spells mem'd: Slow, nuke, SoW

)
3. Regeneration line of spells will be far less effective. If anyone viewed them as "a drop in the bucket" before, wait and see what it's gonna be like when these changes hit.
4. The hit that shaman (and necros, to a lesser degree) will take because of this is *no different* than it would be if, say, every class EXCEPT Wizards got a bunch of low-mana, low-resist, fast-casting, good-damage nukes almost as effective as Wizards get themselves. Wizards would cry foul, and rightly so. We should, too.
Really, it comes down to this: You can't design a class around their ability to regenerate mana, while making them pay for it with mana costs, damage, and general spell effectiveness, AND THEN make every class out there comparable in regen rates. When these changes go live, every level range will change. Canni will become a toy, and not the center of the class that it has been since 1999. If we don't have the advantage of canni, why would anyone want us around most of the time? They should just rename the class "Slow-n-Stats".
