Go ahead, roll up a "Gimpy" character and leave it untwinked until level 8 at least.
If you've already done this recently, just pass on by.
If you are incapable of this and absolutely MUST take 2 or more classes, you fail, don't bother trying again.
I mean things like an Acid/Lightning sorcerer, or a Wizard with 14 INT(Pure.), or a Pure Warforged Monk, or a Pure Rogue Tinker that leans toward melee(enhancements), or a Pure Halfling Repeater Ranger, or a ... you get the drift.
I see too many powerhouses dominating Stormreach, their sole purposes: To grind the hell out of levels below the cap, and some take on the secondary(optional) agenda: e-peen, and disrespecting new players by telling them that they suck because they could not keep up with a min/maxed tome-eating ultratwinked character chugging Haste potions like air.
Come on folks, roll up that Drow Bard Virtuoso with 6 CON!(No ranged feats.) It's called a "challenge" for a reason!
This, of course, is aimed mostly at the people who have 10 Multiclasses and 1 Bard(Spellsinger, Human, Maxed out for Haggle, useless in combat) on their account.
