Want to Start a Rogue and Just want to Make Sure I Understand a Couple Things

[AEH84]

Like the title says, I’ve never played a rogue before and have been doing some research. Can you folks confirm a couple things for me?

1) If im understanding the way haste works, worn haste doesn’t stack. That being the case, there’s no real point in spending a fortune on CoF, Seahorse Belt, etc right? Since Ragebringer would eventually overrule all those anyway? Am I better off with a modest haste item to hold me over like SCHW or FBSS?

2) Regarding weapons, it sounds like high damage in main hand and best ratio in offhand? So something like a Lath in main and a frostbringer or venomous axe in off? What about something like croaking dirk?

3) Lastly, I want to be a gnome. It may not be min max or even good, but I want to be a gnome. That being said, all points into STR or STA? Or split?

Thanks
