Last time I played a rogue was in BC & vanilla, it was my main back then after that druid, DK & paladin were my mains. After few years break from WoW I've come back with a new rogue character. After dinging 90 I geared my rogue very quickly due to Timeless Isle grind & few LRF. I played combat while leveling but didn't manage to get any combat weapons at 90, switched to assassination and got the Timeless Isle daggers.
Now the problem is I've read that the basic rotation for PvE assassination is keeping your SnD & rupture up while spamming mutilate, envenom when on 4-5 CP, dispatch when it procs and under 35% health. Vendetta (with glyph) & Shadow Blades up when possible.
The DPS I manage to do is lousy 60k max. Deadly Poison is on use too.
Because of this I got kicked out of SoO LRF a few times already and not managing getting better weapons (which I hope will solve the problem).
Does assassination suck for raiding? Should I just keep doing raid finder when I get a better weapon by luck? Both my hunter & arms warrior friend win my DPS by far and usually make it in the top 10. D:
