RE: Stealth Perks. Not only does it overpower you early on, but later in the game, they're basically wasted. I've gotten Sneak up to 100 without any perks in it just to check, and you're just as stealthy at that level with no perks as with Stealth (5). Better save those points for elsewhere. As for the rest of them, Muffled Movement is damned near worthless, other than the higher perks on the tree it unlocks. Silent Roll rules, especially combined with Great/Critical Charge if you figure out the timing, and spacing. You can use that combo to backstab someone clear across the room, which is handy if there's multiple targets facing each other. Assassin's blade is OP, but some people like that. Deadly Aim is more than enough, because you can just shoot them long before they have a chance to see you. No need to worry about tricky combos, just shoot, and scoot.. Sneak/Archery is probably the most powerful combination in the game, if you just want to make it boringly easy. Pickpocketing is, of course, a totally different matter. If that's your focus, you may actually want an extra point, or two in Stealth.
