Let me start out by saying, I'm not a rules guy. So please bear with me.
Personally for the cost that it is, what about changing backstab damage to x3 rather than x2? I feel like rogues don't get an opportunity to do half as much back attacking from what I've seen than a fighter, so it makes it much more costly for less overall damage. By changing it to x3 (especially with scaled down damage), it really encourages them to do what they are suppose to be doing.
I also would like to suggest making archery damage scale at x2 rather than x1.5 with backstabs. I like options, and this way a rogue archer is much more viable instead of having to create a fighter archer for the same damage. Options and customizations are good and I don't think this change puts rogue archers above fighter archers in this system.
