Should I master level CoH or upper stab? I made a dual blade during an event where you start out at level 50 and I started playing recently. I didn't know that the job advancement levels got changed so I leveled up a bit and messed up my skill points. I'm a level 75 dual blade that just finished maxing bloody storm and I don't know if I should master coh or not. I currently have 0 points in upper stab but I read that some people use that skill exclusively. Which is better for bossing? CoH feels a little underwhelming to me even with mirror image. Also do people use venom? I only have 4 points in that skill. Thanks for any advice. EDIT: forgot to mention I'm completely unfunded if it matters
