I used to Switch between my Characters like i change clothes
All i can say is: its not a good idea at all
I Ended up Deleting all my lvl 90 instead of the ones that were left on my main server and my very first character (which is a rogue) my rogue is the only character i leveld up to 100 and i started pve with this Expansion (only played pvp before) i can say that assasination is kinda easy to play and has a high dps Output, even with 630 gear (i even wreck Classes with 640 dps wise)
For me its the funniest and also one of the strongest Classes to play, even tho theyre hard to Master (i guess every class is.. But you have Tons of opportunities e.g. In pvp. It all depends on your playstyle)
I use my 90 Toons on my server for the Garnison, gather the resources on a Daily Basis to create bufffood, flasks and pots for my main
Also, mogging for rogues is awesome, if youre into it

Shiny Shiny daggers

not to mention Open pvp with a stealth Class is pure fun
