The point was to nerf hybrid classes, purely because they're waaay too strong right now. A talent should be made available that lowers or even removes the penalty though, that allows hybrids. But as it is right now, warfare characters using scoundrel moves and mages in full plate with no penalty, things like that are whats breaking the game right now. Sure, there's a lot of other things that are overpowered right now, but this is one step towards cutting down on overpowered builds. Hybrids should be possible, but they should also be an investment. As it is right now, you can be a heavy melee spellslinging, adrenaline using hunter-rogue-warrior-mage-nuker from level 1, and thats stupid.
I think these armor changes are an elegant solution to make tanking more lucrative/viable, and to simultaneously nerf some of the overpowered builds right now.
