Yeah I got two sf's and a gloom now on my rogue, seems to work pretty well for me.
I finished my rogue for the most part.

I experimented with different gear and I finally came to enjoy using a balanced set that focuses on crit. After scaling I have 40 percent crit and 299 ap. Much less ap that pure ap builds a lot of people are using, but I think the crit helps a lot and i have 4k hp in bg's and arena which seems to make me live longer so I do more damage to fc's and stuff.
Im still lacking a few items that are a little time consuming to obtain due to my job, like I would love to get a ring of precison, and a charged gear of the tiger, as well as emissary cuffs of the tiger. I would also like to try out a blackvenom blade on offhand. I'm unsure as to whether or not bv blades DOT effect would proc elem force, but if it does that would be great because deadly poison does, so having two dots that both proc elem force would be a great damage increase. I might end up making a new account and then using t to run my rogue through gnomer for the bop items, and I guess next paycheck i could try to buy the boe's off people like i did my gloomshroud and shadowfangs.
I enjoy using my pvp trinket effect for the extra hp, I think it really helps in fights, but ive been unsure whether or not the boa haste trinket might be better to use. The haste bonus is decent and more haste means faster energy regen and more elem force and sf procs, but it would cost me hp. In bg with haste trinket im just over 4k, and using the pvp trink im at like 4.2k. So the question on that is whether or not 200 hp and the bonus health for 15 seconds is better than the haste trinkets dps increase.
Certain items have been trcky for me to decide which is better, such as my boots. The dungeon satchel boots of the bandit provide 1 more crit when in bg's, but i would lose 1 ap. So in this case I chose the ones i have now since i had already achieved my goal of 40 percent crit chance but was still below my goal of 300 ap. This has been the case with most of my items. I have been switching items around trying to achieve the stats I desire, not just going with ''BIS'' items in a slot, but rather going for an end goal.
