Whether you believe it or not, guy, it's still true. Mythic has stated in many different past grab bags that having over 50 effective stealth does nothing for you. 38 stealth is too high too, in my opinion, because you'll have 50 effective stealth at RR2, and it's not that hard to get RR3. That's why most stealthers have their stealth at 35, because RR5 is when your clamped DPS goes up to 16.5 (thus the reason why some ppl refer to their characters as level 51 after RR5), and it's not all that hard to hit RR5.
Your buddy with 35 stealth, what RR is he? If he's not at least RR5, then yes, you probably do walk around faster than he does because he can't hit 50 stealth yet.
You're wasting a lot of spec points that could be put into upping your thrust damage a tad higher. My advice would be to find a career respec stone and use it. Bring your stealth down, you'll thank me later.
