For the Sorc, I'm sure many people with both agree and disagree (depending on thier stace)
But the two 'pets' you can get have one major flaw: If they're not on the bar, they disappear, but that in and of itself is fine.
It's the fact you can't even swap your weapons to your alternate bar, without them vanishing, unless you have them on your other bar too (Including your thunder-calling ult if you went that way)
So technically, to maintain one or both of these pets, they're taking up 2-4 slots TOTAL between both of your bars, which severely limits your choice of active skills on both bars.
Your likely response at this point would be something like: Then don't use the skill!
That's also an option, but what do I propose for this;
Give a short timer, even if you have to dump skillpoints into it, that allows maybe.... 4-6 seconds before they actually dissappear?
This would allow you to swap weapons in combat for a SHORT time, to use skills from your other bar, without losing your pets immediately, and costing you the 4 seconds it takes to summon them both back, while still still forcing you to get back within a set time.
I've noticed no other skill requires it to still be on your bar (that i've seen) to maintain itself. Your Bow volley skill doesn't just dissappear because you swapped to daggers.
Your weapon/armor buffs stay on you when you swap bars, etc.

Right and wrong are not what separate us and our enemies. It's our different standpoints, our perspectives that separate us. Both sides blame one another. There's no good or bad side. Just two sides holding different views. ~Squall Leonheart
