Rogue leveling/skills question

[deven1313]

My rogue is 41 and is skill capped for all the combat skills. It seems like aside from gaining some HPs for every level, there isn't much benefit to leveling at this point until I reach 50 when I can start to increase my skills again. Also since backstab damage is a function of combat skills (Offense, Backstab) , weapon damage, and STR, I will soon reach a hard limit to the amount of backstab (and damage in general,) until 50. If the above is true, it seems quite unbalanced considering casters get new spells as they level while rogues get nada until 50. Am I missing something or is that just the hard reality of being a rogue?
